Abstract
A computer system has processing circuitry to, in a vehicle having a primary stopping system comprising friction brakes and a transmission control unit, and a secondary stopping system with a parking brake system and a propulsion inhibition system, detect a braking action indicating a request to decelerate the vehicle; obtain sensor data indicative of vehicle deceleration; determine, based on the obtained deceleration, whether the primary stopping system is achieving an expected stopping performance; and in response to determining that the vehicle deceleration is below a predefined threshold, activate at least one component of the secondary stopping system to assist in stopping the vehicle.
Claims20
A computer system comprising processing circuitry configured to:
- in a vehicle having a primary stopping system comprising friction brakes and a transmission control unit, and a secondary stopping system comprising a parking brake system and a propulsion inhibition system, detect a braking action indicating a request to decelerate the vehicle;
- obtain sensor data indicative of vehicle deceleration;
- determine, based on the obtained deceleration, whether the primary stopping system is achieving an expected stopping performance;
- and
- in response to determining that the vehicle deceleration is below a predefined threshold, activate at least one component of the secondary stopping system to assist in stopping the vehicle.
A computer-implemented method, comprising:
- obtaining, by processing circuitry of a computer system, data indicative of a braking action indicating a request to decelerate a vehicle having a primary stopping system comprising friction brakes and a transmission control unit, and a secondary stopping system comprising a parking brake system and a propulsion inhibition system;
- obtaining sensor data indicative of vehicle deceleration;
- determining, by the processing circuitry and based on the monitored deceleration, whether the primary stopping system is achieving an expected stopping performance;
- and
- activating, by the processing circuitry and in response to determining that the vehicle deceleration is below a predefined threshold, at least one component of the secondary stopping system to assist in stopping the vehicle.
