Referring to FIG. 1, a general configuration of a starting motor relay control system for safe start according to an embodiment of the present invention will be described first.
  • a start motor relay control system includes a start motor relay for controlling whether a start motor is operated.
  • the starting motor relay is turned on / off as an ECU signal, and the ECU signal for turning on / off the starting motor relay is provided from each part (emergency stop switch, electronic engine, brake sensor, clutch sensor, TCU). Based on the output.
  • the ECU first determines whether the current state of the vehicle satisfies the starting motor driving conditions for securing the safety of the device (starting motor) and the driver, based on the information provided by the respective parts. And outputs a command for connecting the start motor relay only when the information provided from each part satisfies the start motor driving condition inputted in advance.
  • the starter motor relay is connected as such EUC control, the starter motor can be driven by the driver starting operation.
  • the starting motor driving condition recorded in the ECU may be a condition that can ensure the safety of the device (starting motor) and the driver, as briefly mentioned above.
  • 2 is a control logic of the present invention for determining whether the current state of the vehicle meets the starting motor driving conditions. This will be described in more detail with reference to the starting motor driving conditions.
  • the starting motor driving condition is a state in which the engine stops normally and does not operate.
  • the off state of the starting motor relay mapped to the coolant temperature is released. If the engine speed is less than the engine speed, the crankin condition signal (starting condition signal) provided by the TCU is normal, the engine emergency stop signal is not generated, the clutch or the brake is operated, and the fuel injection device is normal.
  • the starter motor relay is turned off during the engine operation so that the starter motor does not run no matter how the operator operates the starter switch. It is possible to prevent the overrun (overrun, the engine that rotates faster than the starter driving the starter upside down) due to the operation of the starter motor while the engine is running, thereby protecting the starting motor.
  • the engine speed is less than the engine speed at which the starter motor relay mapped according to the coolant temperature is turned off, allowing the connection of the starter motor relay, for example, requires that the engine speed be 1100 rpm or more immediately after start-up at a coolant temperature of -20 ° C. This is because the engine stops immediately if the engine speed is less than 1100 rpm immediately after the start even though the coolant temperature is -20 degrees while the driving state is set to be maintained.

In this way, if the driver includes the case where the seat switch is connected by sitting on the seat, the driver can be prevented from starting in a dangerous situation such as when the driver is standing up or starting outside the vehicle.
