Abstract
Provided is a vehicle control method for protecting a vehicle and a driver during forward driving while in reverse gear of an electric vehicle, the vehicle control method including: detecting a gear position of a vehicle; generating a negative torque command to a motor of the vehicle by detecting the gear position as R stage; detecting a vehicle speed of the vehicle; and displaying a warning light or generating a warning sound through a cluster of the vehicle when the vehicle speed is detected as a positive vehicle speed.
Claims11
A vehicle control method for protecting a vehicle and a driver during forward driving while in reverse gear of an electric vehicle, the vehicle control method comprising:
- detecting a gear position of the vehicle as a reverse (R) stage;
- generating a negative torque command to a motor of the vehicle in response to detecting the gear position as the R stage;
- detecting a vehicle speed of the vehicle after generating the negative torque command;
- in response to detecting the vehicle speed as being positive corresponding to the forward driving of the vehicle, displaying a warning light and generating a warning sound through a cluster of the vehicle;
- and
- releasing the warning light and the warning sound in response to operation of a brake pedal of the vehicle by the driver.
A vehicle control system for protecting a vehicle and a driver during forward driving while in reverse gear of an electric vehicle, the vehicle control system comprising:
- a gear detection unit for detecting a gear position of the vehicle;
- a vehicle speed detection unit for detecting a vehicle speed of the vehicle;
- and
- a vehicle control unit for generating a torque command to a motor of the vehicle,
- wherein when the gear position is detected as a reverse (R) stage, the vehicle control unit is configured to generate a negative torque command,
- wherein after the vehicle control unit generates the negative torque command, the vehicle speed is detected by the vehicle speed detection unit, and in response to the vehicle speed being positive corresponding to the forward driving of the vehicle, the vehicle control unit is configured to display a warning light and generate a warning sound through a cluster of the vehicle, and
- wherein the warning light and the warning sound are released in response to operation of a brake pedal of the vehicle by the driver.
