Abstract
A vehicle control device includes a belt slippage determination unit which determines whether or not slippage of a belt has occurred based on rotation of a drive pulley and rotation of a driven pulley, an output state determination unit which determines an output state of a sensor that acquires a signal corresponding to the rotation of the driven pulley, and a speed of rotation limitation unit which controls an upper limit of the speed of rotation of the drive source based on the output state of the sensor when slippage of the belt is detected by the belt slippage determination unit.
Claims10
A vehicle control device that controls a vehicle equipped with a continuously variable transmission, the transmission including a drive pulley, a driven pulley, and a belt that is entrained around the drive pulley and the driven pulley, the vehicle control device comprising:
- a belt slippage determination unit configured to determine whether or not slippage of the belt has occurred based on rotation of the drive pulley and rotation of the driven pulley;
- an output state determination unit configured to determine an output state of a sensor that acquires a signal corresponding to the rotation of the driven pulley;
- and
- a speed of rotation limitation unit configured to limit a speed of rotation of a drive source that drives rotation of the drive pulley;
- wherein, when slippage of the belt is detected by the belt slippage determination unit, the speed of rotation limitation unit controls an upper limit of the speed of rotation of the drive source, on a basis of a determination made by the output state determination unit of the output state of the sensor.
A vehicle comprising a vehicle control device, the vehicle control device controlling the vehicle equipped with a continuously variable transmission, the transmission including a drive pulley, a driven pulley, and a belt that is entrained around the drive pulley and the driven pulley, the vehicle control device comprising:
- a belt slippage determination unit configured to determine whether or not slippage of the belt has occurred based on rotation of the drive pulley and rotation of the driven pulley;
- an output state determination unit configured to determine an output state of a sensor that acquires a signal corresponding to the rotation of the driven pulley;
- and
- a speed of rotation limitation unit configured to limit a speed of rotation of a drive source that drives rotation of the drive pulley;
- wherein, when slippage of the belt is detected by the belt slippage determination unit, the speed of rotation limitation unit controls an upper limit of the speed of rotation of the drive source, on a basis of a determination made by the output state determination unit of the output state of the sensor.
A vehicle control method for controlling a vehicle equipped with a continuously variable transmission, the transmission including a drive pulley, a driven pulley, and a belt that is entrained around the drive pulley and the driven pulley, the vehicle control method comprising:
- a step of detecting slippage of the belt based on rotation of the drive pulley and rotation of the driven pulley;
- a step of determining an output state of a sensor configured to acquire a signal corresponding to the rotation of the driven pulley;
- and
- a step of controlling an upper limit of the speed of rotation of a drive source that drives rotation of the drive pulley, on a basis of the output state of the sensor when slippage of the belt is detected.
