Abstract
A method for braking a vehicle through a redundant braking system includes (i) in response to a fault signal received from the main braking system of the vehicle, obtaining the motor speed, (ii) calculating the wheel speed of the vehicle based on the motor speed, and (iii) generating a braking command based on the wheel speed to control the braking actuators of the vehicle to brake the wheels.
Claims7
A method for braking a vehicle using a redundant braking system, the vehicle including a motor, a transmission operably connected to the motor, a main braking system, braking actuators, and wheels, the method comprising:
- receiving a fault signal from the main braking system;
- obtaining a motor speed of the motor from a resolver sensor operably connected to the motor in response to receiving the fault signal;
- determining a gear position of a plurality of gear positions of the transmission in response to receiving the fault signal;
- calculating a wheel speed of the vehicle based on the motor speed and the gear position;
- and
- generating a braking command based on the wheel speed to control the braking actuators to brake the wheels.
