  • Patent number: 11161524
    Abstract: Disclosed is a vehicle acceleration compensation system, including an accelerator pedal, throttle, and a transmission configured to shift between two or more fixed gears, wherein each gear relates the motor power to a vehicle torque. The system also includes a control unit configured to receive data from one or more sensors. The control unit includes a real-time throttle map relating the accelerator pedal position to the throttle position, such that a given accelerator pedal position directs a corresponding target throttle position, and a real-time shift map relating a desired transmission gear to a current transmission gear, current vehicle speed, and current throttle position, such that a given vehicle speed, given throttle position, and given transmission gear directs a corresponding target transmission gear. In response to sensor data, the control unit updates the throttle map and shift map such that the vehicle torque is altered to produce a desired acceleration value.
