Abstract
An exemplary method includes adjusting a proportion of engine braking used to achieve a target deceleration of a vehicle to change an amount of thermal energy generated from engine braking. An exemplary assembly includes a friction brake to selectively provide friction braking to a vehicle, an engine brake to selectively provide engine braking to the vehicle, and a controller configured to adjust a proportion of the engine braking used to achieve a target deceleration of the vehicle to change an amount of thermal energy generated from engine braking.
Claims21
A method, comprising:
- detecting a target deceleration of a vehicle using a component of the vehicle;
- and
- adjusting, using a controller, a proportion of engine braking used to achieve the target deceleration in order to change an amount of thermal energy generated from engine braking.
A method, comprising:
- adjusting a proportion of engine braking used to achieve a target deceleration of a vehicle in order to change an amount of thermal energy generated from engine braking;
- and
- detecting the target deceleration prior to the adjusting, the target deceleration inferred from a comparison of an actual brake pedal tip out rate to a historical brake pedal tip out rate and corresponding decelerations of the vehicle.
An assembly, comprising:
- a friction brake to selectively provide friction braking to a vehicle;
- an engine brake to selectively provide engine braking to the vehicle;
- and
- a controller configured to adjust a proportion of the engine braking used to achieve a target deceleration of the vehicle in order to change an amount of thermal energy generated from engine braking.
