Abstract

A vehicle control system includes a motor that generates a driving force of a vehicle, an accelerator operation amount sensor that detects an accelerator operation amount, a vehicle speed sensor that detects a vehicle speed; and controller circuitry to determine target acceleration at least on the basis of the accelerator operation amount and the vehicle speed and to control the motor to generate the driving force that corresponds to the target acceleration. The controller circuitry determines target jerk on the basis of the target acceleration or actual acceleration of the vehicle at a time point, at which the accelerator operation amount becomes constant, and the current vehicle speed, and determines the target acceleration to achieve the target jerk when the accelerator operation amount is constant during acceleration of the vehicle.

Dependent claims

A vehicle control system, comprising:

a drive source that generates a driving force of a vehicle;
an accelerator operation amount sensor that detects an accelerator operation amount as an operation amount of an accelerator pedal of the vehicle;
a vehicle speed sensor that detects a vehicle speed of the vehicle;
and
controller circuitry determines target acceleration at least on the basis of the accelerator operation amount and the vehicle speed, controls the drive source to generate the driving force that corresponds to the target acceleration, wherein
the controller is configured to:
determine target jerk on the basis of the target acceleration or actual acceleration of the vehicle at a time point at which the accelerator operation amount becomes constant, and determine the target acceleration to achieve the target jerk when the accelerator operation amount is constant during acceleration of the vehicle;
and
determine the target jerk having a higher value as the target acceleration or the actual acceleration at the time point at which the accelerator operation amount becomes constant is increased.
