Method and apparatus are disclosed for reducing noise caused by a vehicle brake system. An example vehicle includes an adaptive cruise control (ACC) system, a noise cancellation system, a brake system, and a processor. The processor is configured to receive a deceleration request while the ACC is active, determine a braking characteristic based on the deceleration request, determine a noise signal based on the braking characteristic, and output the noise signal via the noise-cancellation system.

Vehicle adaptive cruise control noise cancelation

A controller can display via an instrument cluster a brake capacity based on a temperature of friction material of at least one brake of a vehicle and a predicted brake fade threshold that is derived from a speed, mass, and current angle of inclination of the vehicle.

Brake fade and brake capacity gauge

Method and apparatus are disclosed for adjustment of maximum brake pump speed based on rate of change of target deceleration. An example vehicle includes a brake pump having a maximum pump speed. The example vehicle also includes a vehicle decelerator to determine a target deceleration for autonomous deceleration and send a signal to the brake pump to decelerate the vehicle at the target deceleration. The example vehicle also includes a maximum speed regulator to determine a rate of change of the target deceleration and adjust the maximum pump speed based on the rate of change.

Adjustment of maximum brake pump speed based on rate of change of target deceleration

Method and apparatus are disclosed for adjustment of maximum brake pump speed based on target and measured decelerations. An example vehicle includes a brake pump having a maximum pump speed. The example vehicle also includes a vehicle decelerator to determine a target deceleration for autonomous deceleration and send a signal to the brake pump to decelerate the vehicle at the target deceleration. The example vehicle also includes a first sensor to detect a measured deceleration and a maximum speed regulator to adjust the maximum pump speed based on a difference between the target deceleration and the measured deceleration.

A cruise control system for a vehicle includes a controller configured to maintain a speed of the vehicle about a setpoint, and in response to predicted brake capacity falling below a threshold based on predicted brake fade, reduce the setpoint and downshift a transmission of the vehicle to increase negative torque to reduce brake fade. Also, a powertrain of a vehicle includes an engine, an automatic transmission coupled with the engine, and a controller. The controller is configured to maintain a speed of the vehicle about a setpoint, and in response to a predicted brake capacity falling below a threshold based on predicted brake fade, reduce the setpoint and downshift the transmission to increase a negative torque.
