摘要:
A vehicle brake control system includes an improved ACC system for controlling the operation of a brake actuator and a throttle actuator, based on a signal from a preceding vehicle detector such as a radar device, so that a subject vehicle tracks a preceding vehicle. After a regular brake device is actuated to stop the subject vehicle, an EPB ECU disengages the regular braking device and, instead, actuates an electrically initiated and mechanically maintained parking brake device, so as to temporarily maintain the subject vehicle in a stationary state. Once the electric parking brake device is initiated, its braking state is mechanically maintained even if the flow of current is cut off. Therefore, neither the regular brake device nor the electric parking device consume power while the vehicle is in a stationary state, thereby saving power and minimizing electrical heat generation.

An electric parking brake system that includes a parking brake, and an electric motor, wherein the parking brake is activated by the electric motor. Operation of the parking brake is controlled such that a vehicle is decelerated at a target deceleration of a predetermined magnitude when an operation command to operate the parking brake is issued by a driver via an operation switch while the vehicle is running. If a service brake fails while a vehicle is running, when the driver depresses the operation switch to issue the operation command to a parking brake to brake the vehicle, the parking brake is controlled such that the vehicle is decelerated at the target deceleration of the predetermined magnitude set on the basis of the number of times of depressing the operation switch.

When a shift position is shifted from an R range to a D range and when the shift position is shifted from the D range to the R range, an electrically-operated parking brake device is automatically cancelled. In this manner, the electrically-operated parking brake device is cancelled without waiting for the depression of an accelerator pedal with a driver's intention to start a vehicle taken into consideration. Therefore, it is possible not only to alleviate a burden on the driver in canceling the electrically-operated parking brake device, but also to prevent an abrupt starting of the vehicle due to the cancellation of the electrically-operated parking brake device while the accelerator pedal is being depressed to transmit a large driving force to driven wheels.

A lighting device may include a substrate attached to one edge side of a radiator and a cover may be attached to cover the substrate. Heat-radiating fins may be provided on the other edge side of the radiator and an air-cooling unit may be rotatably provided inside the heat-radiating fins, thereby enabling freely rotation. In one or more examples, a case storing a circuit part is attached to the other edge side of the radiator and a cap is provided to the case. By the air flow from the air-cooling unit, the heat-radiating fins are caused to be a part of the ventilation path to allow for ventilation of the inside of the radiator.

A pitted light diffusive coating having an excellent light diffusion effect and a method of forming the coating and a halogen lamp with the coating are disclosed. The light diffusive coating includes pits on the surface of a continuous coating consisting of a metal oxide formed on a base, and the coating is substantially free of bubbles. The pitted light diffusive coating is formed by coating a base with an organometallic compound and a high boiling-point organic solvent and baking the coating at about 400.degree. C. to 500.degree. C. The halogen lamp has a pitted light diffusive coating formed on an infrared reflective coating on the surface of the outer vessel. Strain, caused by the difference in the thermal expansion coefficient of the structural material of the outer vessel and the structural material of the light diffusive layer occurring when the outer vessel is at a high temperature, is absorbed by the pitted structure, and peeling is prevented.

A substrate is attached to one edge side of a radiator and a globe is attached covering the substrate. Heat-radiating fins are provided on the other edge side of the radiator and an air-cooling unit is rotatably provided inside the heat-radiating fins which enables to freely rotate. A case storing a circuit part is attached to the other edge side of the radiator and a cap is provided to the case. By the wind blast from the air-cooling unit, the heat-radiating fins are caused to be a part of the ventilation path to allow for ventilation of the inside of the radiator.

A halogen incandescent lamp comprises a light-transmitting envelope filled with a gas including a halogen gas and an inert gas. A pair of inner conductive wires is arranged in the envelope. A triple-coiled filament, which has a first coiling, a second coiling, and a third coiling having about 1.5 to about 4 turns, is re-crystallized, is arranged in the envelope, and is connected between ends of the inner conductive wires. The triple-coiled filament is held by a support member. The halogen incandescent lamp may be utilized to a lighting apparatus.
