  • Patent number: 10821999
    Abstract: A vehicle control apparatus includes a deviation detector and a motor controller. The deviation detector is configured to detect a deviation of a host vehicle from a travel lane. Upon the deviation detector detecting the deviation, the motor controller is configured to increase and decrease torque of a driving motor that transfers a driving force to a wheel.
    Type: Grant

  • Patent number: 6832965
    Abstract: A continuously variable transmission having a primary pulley and a secondary pulley on which a belt wound on the primary pulley is fitted. The width of the groove on the primary pulley is adjusted by the oil pressure in the primary hydraulic chamber in the primary cylinder, the width of the groove on the secondary pulley is adjusted by the oil pressure in the secondary hydraulic chamber in the secondary cylinder. The switching operation between the speed change operation in a state in which the line pressure is supplied to the secondary hydraulic chamber and the primary pressure is supplied to the primary hydraulic chamber by the oil passage switching valve, and the speed change control in a state in which the line pressure is supplied to the primary hydraulic chamber and the primary pressure is supplied to the secondary hydraulic chamber can be performed.

  • Patent number: 6306061
    Abstract: Hydraulic pressure generated by an oil pump driven by an engine is regulated to a secondary pressure by means of a secondary pressure control valve. The secondary pressure is employed for controlling a secondary pulley and a primary pulley. On the other hand, the secondary pressure is reduced to a clutch pressure by means of a clutch pressure control valve. The communication between an apply chamber and a release chamber of a torque converter, oil chambers of actuators for a forward clutch and a reverse brake of a forward and reverse changeover apparatus and a clutch pressure line and a lubrication pressure line are controlled by means a switching valve. The clutch pressure is regulated to a high clutch pressure and to a low clutch pressure, respectively by controlling reverse signal pressures supplied to these outer pilot chambers.
