Abstract
Methods and apparatus to control braking of a vehicle during low deceleration operations are disclosed. A disclosed apparatus includes a controller configured to determine a deceleration of a vehicle, compare the deceleration to a threshold, and modulate, at a predetermined frequency, a brake pressure of the vehicle in response to the deceleration being below the threshold.
Claims16
An apparatus comprising:
- a controller configured to:
- determine a deceleration of a vehicle via a deceleration sensor;
- compare the deceleration to a first threshold;
- and
- increase and decrease, at a predetermined periodic frequency via a brake pressure actuator, a brake pressure of the vehicle in response to the deceleration being below the first threshold, wherein the controller is to increase and decrease the brake pressure by generating a sinusoidal or a sawtooth waveform.
An apparatus comprising:
- a controller configured to:
- detect a brake apply operation of a vehicle via a brake apply sensor;
- and
- increase and decrease, at a predetermined periodic frequency via a brake pressure actuator, a brake pressure of the vehicle in response to the detection of the brake apply operation and the brake pressure being below a first threshold, wherein the controller is to increase and decrease the brake pressure by generating a sinusoidal or a sawtooth waveform.
A tangible machine-readable medium comprising instructions which, when executed, cause a processor to at least:
- determine a deceleration of a vehicle via a deceleration sensor;
- compare the deceleration to a first threshold;
- and
- increase and decrease, at a predetermined periodic frequency via a brake pressure actuator, a brake pressure of the vehicle in response to the deceleration being below the first threshold, wherein the controller is to increase and decrease the brake pressure by generating a sinusoidal or a sawtooth waveform.
