Abstract
A drive force control system for a vehicle having a motor and a battery that allows a driver to sense a satisfactory acceleration even if an output torque of a motor is restricted. The drive force control system comprises a controller that calculates an upper limit acceleration of the vehicle based on an upper limit power to be supplied from the battery to the motor. The controller sets a reference jerk as the required jerk when the upper limit acceleration is equal to or greater than the target acceleration, and sets a corrected jerk that is greater than the reference jerk as the required jerk when the upper limit acceleration is less than the target acceleration.
Claims7
A drive force control system for a vehicle having a motor serving as a prime mover, and an electric storage device that supplies electric power to the motor, comprising:
- a controller that controls an output torque of the motor to achieve a required jerk,
- wherein the controller is configured to:
- calculate an upper limit acceleration possible to be established to accelerate the vehicle based on an upper limit electric power possible to be supplied from the electric storage device to the motor,
- set a predetermined reference jerk as the required jerk when the upper limit acceleration is equal to or greater than a target acceleration, and
- set a corrected jerk that is greater than the reference jerk as the required jerk when the upper limit acceleration is less than the target acceleration.
