Abstract
Systems and methods for reducing perception of transitions from shifting a transmission from neutral to drive are described. In one example, the transmission is shifted from neutral to drive in response to brake pedal motion before the brake pedal is fully released so that timing of pressurizing clutches and engaging a forward gear is advanced to occur while the brake pedal is still applied.
Claims14
A driveline operating method, comprising:
- shifting a transmission into neutral from a forward gear via a controller in response to vehicle speed being less than a threshold and a brake pedal being applied;
- and
- shifting the transmission into a forward gear via the controller in response to the brake pedal being released to a position within a threshold distance of top of brake pedal travel.
A driveline operating method, comprising:
- shifting a transmission into neutral from a forward gear via a controller in response to vehicle speed being less than a threshold and a brake pedal being applied;
- and
- shifting the transmission into a forward gear via the controller in response to a vehicle situation awareness sensor indicating a clear travel path in front of a vehicle.
