Vehicle control system

摘要

The vehicle control system controls a vehicle based on an estimated gradient value of a travel road. Further, the vehicle control system includes a front/rear acceleration sensor and wheel speed sensors, and a control device for calculating the estimated gradient value. Further, when the vehicle travels, the control device determines whether or not the vehicle is traveling rearward. Then, when the vehicle is traveling forward, the control device calculates the estimated gradient value based on an output signal of the acceleration sensor and output signals of the wheel speed sensors. In contrast, when the vehicle is traveling rearward, the control device calculates the estimated gradient value based on an output signal of the acceleration sensor.

1. A vehicle control system for calculating an estimated gradient value of a travel road, comprising:
an acceleration sensor that detects an acceleration of a vehicle; wheel speed sensors that detect wheel speeds of the vehicle; and a control device that is configured to:
calculate the estimated gradient value,determine whether the vehicle travels in a first direction or a second direction opposite to the first direction,calculate the estimated gradient value based on an output signal of the acceleration sensor and output signals of the wheel speed sensors at a time the control device has determined that the vehicle travels in the first direction, andcalculate the estimated gradient value based on an output signal of the acceleration sensor without using the output signals of the wheel speed sensors at a time the control device has determined that the vehicle travels in the second direction.
