摘要： A central differential is provided for distributing an output torque of a transmission to front wheels and rear wheels of a vehicle. A fluid-operated restricting device is provided for restricting the differential operation of the central differential. The central differential is arranged to distribute a larger torque to the rear wheels than to the front wheels. A slip ratio of the rear wheels is calculated in dependency on rear-wheel speed and vehicle speed. The fluid-operated restricting device is operated in accordance with the slip ratio, in such a manner that the restricting magnitude increases with an increase of the slip ratio.

摘要： A control system for an electromagnetic clutch for a vehicle has an engine speed sensor, a clutch driven member speed sensor and a throttle position sensor. The system has a memory storing first torque capacities increasing with increase of engine speed and storing second torque capacities at clutch engagement rate 100% in accordance with engine speed and throttle position. The actual clutch engagement rate is calculated based on output signals of the engine speed sensor and the clutch driven member speed sensor. A first torque capacity and a second capacity are derived from the memory in accordance with output signals of the sensors. A torque capacity Tc for engaging the clutch is calculated as follows,Tc=Re.multidot.TcL+(1-Re).multidot.Tcswhere Re is the clutch engagement rate, Tcs is the first torque capacity and TcL is the second torque capacity.

摘要： A sensor failure and erroneous signal detection system for use in automobiles equipped with cruise control. This system prevents cruise control from operating if certain predetermined conditions occur. Further, the system will determine if the cruise control signal has been erroneously generated and set up an error "flag". A failure is determined in the cruise control system if either one of the following conditions is present when a cruise control signal is generated: (1) the vehicle is traveling below a predetermined speed; (2) the brake switch is on; (2) the shift range is in "N", "R" or "P"; or (4) either (1), (2) or (3) continues for a predetermined period of time. Upon occurrence of (1), (2), (3), or (4), an error has been detected and the automatic transmission is instructed to return to normal operation.

摘要： A planetary gear device as a central differential distributes an output torque of a transmission to the front wheels and the rear wheels of a four-wheel drive motor vehicle. A fluid operated clutch is provided between a sun gear and a ring gear of the planetary gear device. A desired speed ratio between front-wheel speed and rear-wheel speed at cornering is calculated based on vehicle speed and steering angle of the vehicle. A torque distribution ratio is determined in accordance with a difference between the desired speed ratio and an actual speed ratio between the front-wheel speed and the rear-wheel speed. The clutch pressure is controlled in response to the torque distribution ratio for engaging the clutch so that the average speed ratio coverages to the desired speed ratio.

摘要： A torque distribution deciding control unit, a planetary gear device as a central differential and an oil hydraulic clutch having opposite disks are provided on a motor vehicle. The clutch is disposed between output members of the planetary gear device, whereby torque is transmitted to front and rear wheels at a distribution ratio decided by clutch torque of the clutch. The control unit operates the clutch so as to distribute the torque at a ratio in accordance with slipping of the front or rear wheels so as to reduce the torque for the slipping wheels.

摘要： A central differential distributes output torque of a transmission to front wheels and rear wheels of a vehicle. A fluid-operated restricting device is provided for restricting the differential operation of the central differential. The central differential is arranged to distribute a larger torque to the rear wheels than that to the front wheels. A slip ratio of the rear wheels is calculated, and a desired slip ratio is set based on driving conditions of the vehicle. A slip ratio deviation of the rear-wheel slip ratio from the desired slip ratio is obtained. The fluid-operated restricting device is operated in accordance with the slip ratio deviation, in such a manner that the restricting magnitude increases with an increase of the slip ratio deviation.
