摘要： A magnetic rotation detector includes a magnetic rotor having magnetic bodies, a detecting body that detects a change in magnetic flux that is caused by the magnetic bodies as the magnetic rotor rotates; and an abnormality determination portion that monitors an apparent fluctuation in rotational speed of the magnetic rotor based on a result detected by the detecting body and that determines that the magnetic rotor is in an abnormal state if the fluctuation occurs at a specific position of the magnetic rotor. The abnormality determination portion detects the occurrence of the fluctuation at the specific position of the magnetic rotor by making a determination on a distance between apparent positions of the magnetic bodies which correspond to the apparent fluctuation in rotational speed and calculates the distance on the basis of a product of an interval of generation of noise in an output signal detected by the detecting body and a rotational speed of the magnetic rotor at the time of generation of noise.

摘要： The present invention is directed to a front-rear braking force distribution control system for a vehicle. The system includes a wheel brake cylinders operatively associated with front and rear wheels of the vehicle, a pressure generator for pressurizing brake fluid in response to operation of a brake pedal to generate a hydraulic braking pressure and supply it to each of the wheel brake cylinders, and a pressure control device disposed between the pressure generator and the wheel brake cylinders for controlling the braking pressure in each of the wheel brake cylinders. A pressure sensor is provided for detecting the braking pressure generated by the pressure generator, and the detected braking pressure is compared with a predetermined threshold pressure. The braking force control device provides conditions for beginning the front-rear braking force distribution control, including at least a condition for beginning the front-rear braking force distribution control, when the detected braking pressure exceeds the predetermined threshold pressure, which may be set in accordance with a pressure increasing rate of the braking pressure.

摘要： A vehicle running control apparatus for executing a turn assist control which controls longitudinal forces of wheels so that longitudinal force of a turning inner wheel is lower than longitudinal force of a turning outer wheel by lowering the longitudinal force of the turning inner wheel. The lowering of the longitudinal force of the turning inner wheel is made more difficult to be started and a lowering amount of the longitudinal force of the turning inner wheel is set smaller when difficulty in driving vehicle by wheel drive forces is high as compared with the case where the difficulty in driving vehicle is low. The difficulty in driving vehicle includes at least one of resistance against vehicle movement by wheel drive forces and difficulty in transmitting driving forces from wheels to road surface.

摘要： Each of target braking forces for front and rear wheels of a vehicle is calculated based on an amount of braking performed by a driver and a predetermined braking force distribution ratio between the front wheels and the rear wheels. Each of the target regenerative braking forces for the front and rear wheels, respectively, is calculated based on a corresponding one of the target braking forces such that a maximum regeneration efficiency is obtained. If the driver has performed an abrupt braking operation, if the driver has performed a braking operation when the vehicle runs at a high deceleration, or if the vehicle runs at a high lateral speed, it is quite likely that anti-skid control will be started afterwards. Therefore, the target regenerative braking forces are gradually reduced, and target frictional braking forces are gradually increased. If anti-skid control is started, the target regenerative braking forces are set as 0.

摘要： A target wheel cylinder pressure for each wheel is calculated according to an amount of braking operation performed by a vehicle operator. When anti-skid control is required, the wheel cylinder pressure is controlled to be equal to the target wheel cylinder pressure for reducing the brake slip of the wheel. When one of the rear-left and the rear-right wheels is anti-skid controlled, the target wheel cylinder pressure for the other wheel for which the anti-skid control is not performed is set to the same value as the target wheel cylinder pressure for the wheel for which the anti-skid control is performed. Linear valves are controlled based on the target wheel cylinder pressure, controlling the wheel cylinder pressures for the rear-left and the rear-right wheels to have substantially the same value.

摘要： A control state of the vehicle is switched upon operation of a control switch. Besides, a mode of travel for a travel of a vehicle is selected by operation of a travel mode selection portion.
