Abstract
Methods, systems, and apparatus for a continuously adaptable braking pedal system. The braking system includes an electric motor that is configured to generate regenerative energy and provide a regenerative braking torque. The braking system includes an electronic control unit coupled to the electric motor. The electronic control unit is configured to determine an amount of the regenerative braking torque to be applied based on an adaptable pedal map and an amount of braking force. The electronic control unit is configured to control an amount of the regenerative braking torque to be applied.
Claims17
A braking system, comprising:
- an electric motor that is configured to generate regenerative energy and provide a regenerative braking torque;
- a memory configured to store a plurality of pedal maps, each pedal map having a different mapping of regenerative braking torque, engine or motor speed, and brake pedal position;
- and
- an electronic control unit coupled to the electric motor and the memory and configured to:
- select a pedal map from the plurality of pedal maps,
- determine an amount of the regenerative braking torque to be applied based on the selected pedal map and an amount of braking force, and
- control an amount of the regenerative braking torque to be applied.
A braking system, comprising:
- an electric motor that is configured to generate regenerative energy and provide a regenerative braking torque;
- an inverter coupled to the electric motor and configured to control the regenerative braking torque of the electric motor;
- a memory configured to store a plurality of pedal maps, each pedal map having a different mapping of regenerative braking torque, engine or motor speed, and brake pedal position;
- and
- an electronic control unit coupled to the inverter and the memory and configured to:
- select a pedal map from the plurality of pedal maps,
- determine an amount of the regenerative braking torque to be applied based on the selected pedal map and an amount of braking force, and
- provide a signal that indicates the amount of regenerative braking torque to be applied.
A method of controlling a deceleration force of a vehicle, comprising:
- storing, in a memory, a plurality of pedal maps, each pedal map having a different mapping of regenerative braking torque, engine or motor speed, and brake pedal position;
- determining, by a processor, that the vehicle is coasting or decelerating;
- selecting, by the processor, a pedal map from the plurality of pedal maps;
- determining, by the processor, the amount of regenerative braking torque to be applied based on the selected pedal map;
- and
- controlling, by the processor and using an inverter, the amount of regenerative braking torque.
