Abstract
A method adjusts a brake pedal characteristic of a vehicle having a brake pedal configured to generate a brake pedal deceleration demand and at least one further deceleration demand generating device to generate at least one further deceleration demand. The vehicle is configured to decelerate according to the brake pedal deceleration demand and to the at least one further deceleration demand. The method determines an achievable deceleration potential as a result of the further deceleration demand; generates a deceleration demand for adjusting the brake pedal deceleration demand at 0% brake pedal input according to the achievable deceleration potential; and adjusts the brake pedal characteristic of the vehicle.
Claims17
A method for adjusting a brake pedal characteristic of a vehicle, wherein the vehicle comprises a brake pedal configured to generate a brake pedal deceleration demand and a further deceleration demand generating device to generate the further deceleration demand, wherein the vehicle is configured to decelerate according to the brake pedal deceleration demand and to the further deceleration demand, wherein the method comprises the steps of:
- (S1):
- determining an achievable deceleration potential as a result of the further deceleration demand;
- (S2):
- generating a deceleration demand for adjusting the brake pedal deceleration demand at 0% brake pedal input according to the achievable deceleration potential;
- and
- (S3):
- adjusting the brake pedal characteristic of the vehicle.
A device for adjusting a brake pedal characteristic of a vehicle, comprising:
- an interface for receiving input data comprising a deceleration demand and/or an achievable deceleration potential;
- an interface for providing output data comprising a target brake pedal characteristic and/or signals for adjusting the brake pedal characteristic;
- and
- a data processing unit configured to:
- determine the achievable deceleration potential as a result of a further deceleration demand;
- generate a deceleration demand for adjusting the brake pedal deceleration demand at 0% brake pedal input according to the achievable deceleration potential;
- and
- adjust the brake pedal characteristic of the vehicle.
A computer product comprising a non-transitory computer readable medium having stored thereon program code which, when executed on a data processing unit, carries out the acts of:
- (S1):
- determining an achievable deceleration potential as a result of a further deceleration demand;
- (S2):
- generating a deceleration demand for adjusting the brake pedal deceleration demand at 0% brake pedal input according to the achievable deceleration potential;
- and
- (S3):
- adjusting the brake pedal characteristic of the vehicle.
