Definitions

  • the invention relates to a brake-by-wire system for fail-safe operation of a vehicle using zone control devices.
  • the driver's braking request is usually read out via the brake pedal.
  • the brake pedal acts directly on the hydraulics that control the brakes, or an electronic brake pedal sends a signal to the hydraulics that control the brakes.
  • electrohydraulic brakes for passenger cars and electronic brake systems for commercial vehicles are known.
  • electrohydraulic brakes are dependent on hydraulics comprising hydraulic units, pressure accumulators and hydraulic lines and thus comprise several components and mean a higher weight load, which is particularly disadvantageous in the context of electric vehicles.
  • electromechanical or electromagnetic brakes in the form of brake-by-wire systems appear to be advantageous, in particular with regard to the resulting weight savings due to the omission of hydraulic components.
  • brake-by-wire systems a higher probability of failure can be assumed due to the restriction to electrical signals.
  • the object of the invention was how a fail-safe brake-by-wire system can be implemented.
  • a first zone control device which can be arranged in a first area of the vehicle, operates functions of first vehicle components present at least in the first area and regulates and/or controls the first vehicle components;
  • a second zone controller that can be arranged in a second area of the vehicle, operates functions of second vehicle components that are present at least in the second area, and regulates and/or controls the second vehicle components;
  • an actuating device which, in the event of a failure of the data connection, a gateway between the first and the second zone control device, in the event of a failure of the first zone control device and/or part of the first vehicle components, a gateway to the second zone control device, or in the event of a failure of the second zone control device and/or part of the second vehicle components forms a gateway to the first zone control device, wherein at least part of the first and/or part of the second vehicle components can be regulated and/or controlled via the gateway.
  • a brake-by-wire system is an x-by-wire system in which a braking request is not transmitted mechanically but via signals.
  • X-by-wire refers to the replacement of mechanical connections, signals and systems for manual control by the conduction of electrical, electronic, optoelectronic or optical control signals between the operating elements used and the executive actuators, for example fly-by- Wire from the fact that the control impulse between the control stick and the rudder is no longer transmitted mechanically in the airplane as was previously the case.
  • the content of the preceding sentence is taken from Wikipedia and is licensed under the CC-BY-SA license.
  • a zone controller or zone controller controls several assemblies or vehicle components in a zone of the vehicle, for example a front zone controller controls the brake actuators of the front vehicle wheels, the front lighting, the front vehicle indicators and an entertainment system.
  • a rear zone controller controls, for example, the brake actuators on the rear vehicle wheels, the rear lights and the rear vehicle indicators.
  • the zone control unit forms a node, for example a node in a vehicle electrical system, for example for the data connections and power distribution to sensors, actuators, peripheral devices and external assemblies in its vicinity. This reduces the number of control units. Strategic placement in the zone reduces cabling complexity and/or cost, in accordance with one aspect of the invention. Reducing the number of controllers also reduces the number of coolers required for the controllers.
  • the zone controller includes only one chiller. This saves power, which is particularly advantageous in hybrid electric vehicles and/or electric vehicles with regard to battery power.
  • energy distribution in such a zone architecture in which sensors and/or peripheral devices are connected to the nearest zone controller, individual functions that the zone controller operates can be temporarily switched off, for example the entertainment system, in order to save energy.
  • the use of two zone controllers increases redundancy in the system.
  • the first area of the vehicle is, for example, the front area of the vehicle in a forward direction of travel of the vehicle.
  • the second area of Vehicle is, for example, the rear area of the vehicle in a forward direction of travel of the vehicle.
  • the driving dynamics data include the speed and acceleration of the vehicle.
  • the sensors that measure the vehicle dynamics data include wheel speed sensors, according to one aspect with direction of rotation sensing, yaw rate and lateral acceleration sensors, steering angle sensors, inertial measurement units, also called inertial measurement units, radar and/or lidar sensors. These sensors provide data on speed, the state of movement of the wheels, driving conditions such as cornering, and the distance to the vehicle in front for adaptive speed control, also known as adaptive cruise control. According to one aspect of the invention, the required measuring technology is integrated in a zone control device.
  • This data is made available to both zone controllers via the data connection.
  • the data connection is fiber optic.
  • a gateway is a hardware and/or software component that establishes a connection between two systems.
  • the term gateway implies that the forwarded data is processed.
  • the content of the previous two sentences is taken from Wikipedia and is subject to the CC-BY-SA license.
  • the actuating device thus solves a possible failure in the data line via the gateway.
  • the first and/or the second zone control device includes middleware.
  • Computer programs for regulating and/or controlling the first and/or second vehicle components register via the middleware.
  • Middleware is an application-neutral program that mediates between applications and operating systems from hardware modules. Using the middleware, applications or also called applications can be used independently of a hardware module, for example a control unit.
  • the zone control devices implement a service-oriented architecture, which is particularly advantageous in connection with software defined cars, in particular E/E architectures of electric vehicles.
  • system is characterized in that
  • the actuation can either be routed directly from a primary control unit to all brake actuators 11 , 12 , 21 , 22 .
  • the second vehicle components 21 , 22 comprising a second brake actuator 21 for the rear right brake and a second brake actuator 22 for the rear left brake, are controlled at the rear via the second zone control device 20 .
