Definitions

• the present subject matter described herein generally relates to a vehicle, and particularly but not exclusively relates to a display unit of a vehicle.
• an instrument cluster or a speedometer is a gauge that acts as a display unit of a vehicle and displays the instantaneous speed of the vehicle along with other features.
• speedometers were called eddy current speedometers but they were later replaced by modern electronic speedometers, because of certain disadvantages, such as they were incapable of showing the vehicle speed when the vehicle was running in reverse gear.
• These modern electronic speedometers mostly include a rotation sensor mounted in the transmission that delivers a series of electronic pulses whose frequency corresponds to the average rotational speed of the driveshaft of the vehicle, and therefore the vehicle's speed is displayed, assuming the wheels have full traction.
• the sensor is typically a set of one or more magnets mounted on the output shaft or (in transaxles) differential crown wheel or a toothed metal disk positioned between a magnet and a magnetic field sensor. As the part turns, the magnets or teeth pass beneath the sensor, each time producing a pulse in the sensor as they affect the strength of the magnetic field it is measuring.
• ABS Antilock Brake System
• a computer converts the pulses to a speed and displays this speed on an electronically controlled, analog-style needle or a digital display.
• Pulse information is also used for a variety of other purposes by the Electronic Control Unit (ECU) or full-vehicle control system, e.g. triggering ABS or traction control, calculating average trip speed, or to increment the odometer in place of it being turned directly by the speedometer cable.
• ECU Electronic Control Unit
• full-vehicle control system e.g. triggering ABS or traction control, calculating average trip speed, or to increment the odometer in place of it being turned directly by the speedometer cable.
• Another early form of electronic speedometer relies upon the interaction between a precision watch mechanism and a mechanical pulsator driven by the vehicle's wheel or transmission.

• Fig. 8 illustrates a display surface orthogonal view of a display unit of a two wheeled vehicle, in accordance with an alternate embodiment of the present invention.
• the leaning of the vehicle by the rider to keep the vehicle in balance mostly depends upon the factors such as the angle of the corner, the velocity of the vehicle, riding surface, tyre surface condition, and the vehicle’s weight. This calculation is basically done by the rider in form of a judgment on the turning moment of the vehicle, which is achieved by the rider’s previous learning and experiences.
• the knowledge of the maximum safe lean angle of the vehicle aids in unlocking the maximum speed potential of a vehicle. The farther the rider can lean the vehicle, the higher potential corner speed can be achieved. But the maximum lean angle reached should be limited with due consideration of the safety of the rider as well. Because as soon as the rider crosses the safe range of the lean angle of the vehicle, the vehicle would trip causing severe accidents and therefore compromising the safety of the rider and the vehicle.
• the leaning angle of the vehicles, particularly a motorcycle relatively varies according to the motorcycle type and mode of riding, which makes the maximum safe lean anglein motorcycles different for every segment of the motorcycle.
• the maximum safe lean angle of a racing bike is much higher and different than the street sports or regular street bikes.
• Most street sports or regular street bikes can safely lean up to a lean angle of 35 degrees, however racing motorcycles can safely lean over 60 degrees.
• the lean angle is sensed by a lean angle sensor attached to the vehicle which senses and detects the leaning angle of the vehicle.
• the lean angle sensor depending upon the data received by the lean angle sensor, if the vehicle detects surpassing of a prefixed safe margin of the lean angle, then the engine power is automatically cut down, to minimize internal mechanical hazard and to reduce the severity of the accident because of the spinning wheel and the speed of the vehicle.
• the lean angle sensor also sends angle data to the motorcycle engine control unit (ECU).
• the ECU in such vehicles responds to the angle data and takes necessary safety and control measures. These control measures include controlling traction control, ABS control on corners, and wheel control in lean condition, etc.
• the lean angle of a vehicle is digitally displayed on a digital instrument cluster.
• the area in which the lean angle is displayed in such vehicles is usually in the bottom right most corner of the instrument cluster.
• the area of the instrument cluster utilized for the display of the lean angle is considerably small when compared to the area of the instrument cluster utilized for the display of the speed of the vehicle.
• the rider shifts his focus from the road to the instrument cluster. Doing so usually takes the focus of the rider away from the road for an extended period of time because of the location and the size of the font of the lean angle display.
• This extended shift of focus from the road to the instrument cluster can be detrimental for the rider, as while looking at the corner of the instrument cluster while observing the instantaneous lean angle taken, sometimes the body of the rider also slightly moves towards the direction in which the lean angle is displayed. Resultant to which the rider fails to align his body in the direction in which the vehicle is moving which can further lead to unbalancing of the vehicle and thus can lead to detrimental accidents.
• the display of the angle is disposed centrally on the display unit, it may still hamper ergonomic viewing of the lean angle when the rider has leaned in one of a left and right direction.
• this makes it a moving target challenge to display the lean angle information to the rider is an ergonomic way such that it is promiscuous across the range of movement of the vehicle as well as the rider and thereby achieve safety of the rider by displaying the required information in a manner in which the rider can process it effectively within a fraction of time.
• the present subject matter relates to a display unit of a vehicle, for example an instrument cluster, comprising a first region and a second region.
• the first region is closer to a boundary of the display unit and the second region is farther from the boundary of the display unit.
• the second region of the display unit displays a lean angle taken by the vehicle. The displayed lean angle on the display unit, proportionately shifts based on the direction of the lean of vehicle.
• the lean angle indication is user controlled.
• the instrument cluster of the vehicle provides the rider the option of choosing between the display options of a second indication, for example an average speed of the vehicle and the lean angle of the vehicle.
• a controller receives the input of activation of lean angle indication or lean graph and the lean angle is accordingly displayed.
• a first indication for example an engine speed data display, is displayed when the controller does not receive input of activation of lean angle indication or lean graph by rider.
• the lean angle of the vehicle is capable of being displayed in numeric form or in graph form.
• the space utilized for the display of the lean angle in bar or lean graph can be the topmost portion of the instrument cluster or also can be the bottom most part of the instrument cluster.
• the display of the bar or lean graph of the lean angle is indicated on the side on which the vehicle is taking the lean angle.
• the rider can assess his riding performance by having a glance at the lean angle in a fraction of time and the information is depicted in form of bars on the right hand side of the instrument cluster, when he is taking a lean angle towards his right hand side, when viewed from a rider’s perspective when rider is riding the vehicle.
• the rider can assess his riding performance by having a glance at the lean angle and the information is depicted in form of bars on the left hand side of the instrument cluster, when he is taking a lean angle towards his left hand side, when viewed from a rider’s perspective when rider is riding the vehicle.
• the lean angle when the rider is riding the vehicle in either left or right direction within a predetermined range, the lean angle is displayed near the centre of the display unit along a vertical axis.
• the vehicle has a lean angle within a predetermined range of 15 degrees on either right or left side of the vehicle, the lean angle is displayed near the centre of the display
• the display of the lean angle dynamically shifts towards the right hand side of the vehicle proportionally based on direction of the lean of the vehicle.
• the display of the lean angle dynamically shifts towards the left hand side of the vehicle proportionally based on direction of the lean of the vehicle.
• the font size of the lean angle display increases proportionately based on the lean of the vehicle.
• the proportionate increase in the font size aids in combating the problem of the poor visibility of the lean angle taken by the rider while leaning the vehicle.
• the display unit of a vehicle multiplexes the lean angle data display with a first indication, for example an engine speed data display.
• the instrument cluster of the vehicle is capable of storing maximum lean angle taken by the rider during or post completion of a ride and display logged data to the user on demand.
• the instrument cluster of the vehicle is capable of storing last lean angle taken by the rider during or post completion of a ride.
• the instrument cluster of the vehicle includes a range of predefined color codes, which depict the status of the lean angle taken by the rider. For example, the instrument cluster displays green color when the lean angle taken by the rider is within a predetermined range; the instrument cluster displays yellow color when the lean angle taken by the rider is about to cross the predetermined range; and the instrument cluster displays red color when the lean angle taken by the rider is beyond the predetermined range and calls for retracting thereby ensuring safety limits and enabling to achieve safe ride by the rider.
• These predetermined ranges can be customized according to the type of the vehicle being ridden, or according to the maximum safe possible lean angle that can be taken by the rider, or according to the level of experience of the rider himself.
• the lean graph or bar form of lean angle depiction and digital depiction of lean angle can be displayed together on an instrument cluster.
• the instrument cluster of the vehicle can be a circular instrument cluster.
• the lean angle can be displayed in an analogue instrument cluster using a separate needle.
• a vehicle warning system is activated to caution the rider and potentially minimize the harm that may be caused to the vehicle or the rider owing to an impending accident.
• position of the lean graph on display unit is customizable by a rider.
• the display of the lean angle taken by the rider on the instrument cluster in accordance to the direction in which the vehicle is leaning it enables the rider to quickly glance at the speedometer while taking the lean angle, without having to shift his concentration from the road for an extended period of time.
• the display of the lean angle is read by the rider on the instrument cluster in lean graph or bar form of lean angle depiction and the digital form of lean angle depiction which gives a prominent visual indication of the instantaneous lean angle and further reduces the time which the rider requires to quickly glance at the speedometer while taking the lean angle, without having to shift his concentration from the road for an extended period of time.
• the lean angle display as suggested by the prior discussed embodiments aids in proving comfort to the rider when he requires to assess his performance by noting the lean angle taken by him as well as enhances the aesthetics of the instrument cluster because of the different display techniques disclosed.
• the lean angle display as disclosed in the embodiments uses fewer microcontroller pins in the instrument cluster thus reducing overall cost of the instrument cluster.
