A braking force retaining unit, which retains braking force until driving force for starting a vehicle increases to a certain value such that the braking force continues to act on the vehicle after releasing a brake pedal, wherein said braking force retaining unit having a device for decreasing the braking force in accordance with the increasing driving force.

Braking force retaining unit

A brake fluid pressure retaining unit for a vehicle comprises a solenoid valve SV arranged in a brake fluid passage FP between a master cylinder MC and a wheel cylinder WC so as to shut off or communicate the brake fluid passage FP. In the case that a transmission of the vehicle is shifted to a driving position, the solenoid valve SV is switched to a shut-off position when the vehicle stops with a brake pedal BP depressed. The solenoid valve SV is switched to a communicating position when driving force is exerted on the vehicle. Brake fluid pressure is retained within the wheel cylinder WC when the solenoid valve SV is in the shut-off position. The brake fluid pressure within the wheel cylinder is retained after releasing the brake pedal so that braking force continues to act on the vehicle. The brake fluid pressure retaining unit comprises control means CU such that when the solenoid valve is in the shut-off position and the transmission is shifted to a non-driving position, the solenoid valve SV is returned to the communicating position on condition that depression of the brake pedal BP is released.

Brake fluid pressure retaining unit

A braking force control unit, which allows transmission of driving force from a motor to driving wheels irrespective of releasing an accelerator pedal under or equal to a certain vehicle speed when a transmission is selected to a driving range, and switches said driving force to be transmitted to the driving wheels between a strong condition and a weak condition in accordance with depression of a brake pedal such that when the brake pedal is depressed, said driving force is controlled to be less than the driving force upon releasing the brake pedal, wherein the braking force control unit comprises means for retaining braking force so as to continuously retain the braking force after releasing the brake pedal, and said means releases the braking force after releasing the brake pedal and in the process of increasing the driving force to the strong condition.

In a continuously variable transmission, a speed change control device includes a vehicle speed sensor, a brake sensor, a release vehicle speed memory which, when the brake is operated, renews and stores the brake release vehicle speed, and a gradient sensor for detecting a running road gradient. When, in an engine brake running state, the present vehicle speed is higher than the brake release vehicle speed stored in the release vehicle speed memory, a speed change target value is obtained according to the difference between the present vehicle speed and the brake release vehicle speed and to the road gradient. And, when, in the same state, the present vehicle speed is lower than the brake release vehicle speed, the speed change target value is obtained according to the road gradient. The speed change control is carried out so as to obtain the speed change target value.

Speed change control device for vehicular continuously variable

Water proofing of a water-proof connector is achieved in such a manner that terminals (3) are inserted into a connector housing (1), the terminals (3) are locked inside the housing (1) by means of a retainer (9), and a rubber plug (5) is press fitted in the housing (1). At this time, a detection pin (10) of the retainer (9) is caused to be inserted in a hole (21) of the rubber plug (5), and the distal end of the pin (10) slightly projects from the hole (21). This allows one to see that the terminals (3) are properly received in the housing (1).
