A method of braking force distribution and a braking force control system for a vehicle provide a proper control on distribution between braking force between front wheels and rear wheels by controlling braking force on a rear right wheel and a rear left wheel such that an actual wheel speed of each rear wheel follows a target wheel speed thereof. The method includes the steps of calculating a current target wheel speed of each rear wheel to be used based on an actual deceleration speed of at least one of the front wheels and a previous target wheel speed of each rear wheel; and controlling braking force on each of the rear wheels based on the thus calculated current target wheel speed.

An apparatus for quickly and accurately determining a counter steer state of a vehicle is provided. The apparatus comprises a turning direction obtaining unit 70 obtaining a turning direction of a vehicle, an oversteer state determination unit 71 determining whether the vehicle is in an over steer state, a steering angle based yaw rate obtaining unit 72 obtaining a steering angle based yaw rate to be determined based at least on a steering angle, a lateral acceleration based yaw rate obtaining unit 73 based at least on a lateral acceleration, a counter steer state determination unit 74 determining that the vehicle is in a counter steer state against the vehicle turning in the vehicle turning direction if the steering angle based yaw rate obtained by the steering angle based yaw rate obtaining unit 72 is smaller than the lateral acceleration based yaw rate obtained by the lateral acceleration based yaw rate obtaining unit 73 when the oversteer state determination unit 71 determines that the vehicle is in the oversteer state for the vehicle turning in the vehicle turning direction obtained by the turning direction obtaining unit 70.

A brake pressure controller for a vehicle is provided which can reliably restrain the difference between the left and right brake pressures from becoming excessively large. A controller 52 of a vehicle brake pressure controller includes an allowable differential pressure setting device 52A for setting an allowable differential pressure between the left and right wheels based on parameters indicating a motion state of a vehicle, a target control pressure setting device 52B for setting a value obtained by summing up the allowable differential pressure set by the allowable differential pressure setting device 52A and a lower-friction-side brake pressure as a target control pressure of a higher-friction-side brake pressure, and a higher-friction-side brake pressure control device 52E for adjusting the higher-friction-side brake pressure to the target control pressure.

A stereoscopic optical system includes, at a distal end of an insertion part of an endoscope, a two-path forming optical system for forming two paths of rays involving a parallax, an image forming optical system for forming images out of light travelling along the respective paths of rays in the two-path forming optical system onto a common region, and an image sensor arranged at an image forming position of the image forming optical system. The stereoscopic optical system is further provided with a time-division path switching means that is capable of switching between the two paths of rays in a time-division manner so that only light coming from either one of the two paths of rays formed by the two-path forming optical system enters the image forming optical system.

An endoscope system has a light source apparatus and an endoscope including an illumination optical system and an objective optical system. At least the objective optical system of the endoscope is provided with an adjustable diaphragm, and in a light path in one of the light source apparatus, the illumination optical system, and the objective optical system, an insertable/retractable filter for observation for special light is provided. The adjustable diaphragm performs a closing operation or an opening operation only when the filter for observation for special light is inserted into the light path.
