In an on-vehicle electric power source system, a power source control device is configured to supply an electric power from an electric power supply source to an actuator by means of a dual-circuit power supply line. The dual-circuit power supply line includes a bypass line and a charge-up line arranged in parallel with the bypass line. A first shut-off circuit is disposed in the bypass line. A booster circuit, an electricity storage device, and a second shut-off circuit are disposed in the charge-up line. The storage device is provided for storing an electric power boosted up by the booster circuit. Also provided is a control unit, which is configured to perform switching between an electric power supply through the bypass line and an electric power supply through the charge-up line by a changeover of a shutoff-circuit established/blocked state between the first and second shut-off circuits.

A brake device includes an actuator which is provided on a wheel side of a vehicle having a suspension, the actuator generates a braking force by being electrically driven. A drive controller is also provided for receiving a signal regarding the braking force from a vehicle motion controller and sensors, and driving the actuator accordingly. To reduce the number of high cost bending wires necessary to communicate between the sensors, the drive controller and the vehicle motion controller, the drive controller and the sensors are attached to the actuator side (unspring-mass).

At least one of first and second actuator driving devices is supplied with electric power securely. When failure occurs in any one of main power line, auxiliary power line, first and second power supply lines and first and second relays, the first to third relays are controlled to be opened and closed so that failure part is separated or failure part is isolated from part where failure does not occur or supply of electric power to failure part is cut off or electric power is supplied to part to which electric power cannot be supplied.

The invention provides a grease composition comprising a base oil consisting of a fluorinated oil and an antirust agent, wherein said antirust agent comprises an aliphatic dibasic acid salt of the formula (1) in an amount of not less than 0.1% by mass and less than 1.0% by mass based on the total mass of the grease composition: (CH2)n(COO)2Mm (1) wherein n is an integer of 1 to 19, M is an alkali or alkaline earth metal, m is 2 when M is an alkali metal and m is 1 when M is an alkaline earth metal, and a bearing wherein the grease is packed. The grease exerts less effects on the environment. It is low in evaporation loss at a high temperature, shows good antirust property and can be suitably used in a ball bearing operated at a high temperature.

A brake apparatus is provided that can make a ratio between a front wheel braking force and a rear wheel braking force that is actually generated into an arbitrary ratio. This brake apparatus includes a pedal operation detection section that detects a pedal stroke or a brake pedal force produced by a brake pedal operation; a brake caliper that is provided in each wheel of a vehicle and that generates a caliper force that is in accordance with a detection value of the pedal operation detection section; a load estimation section that estimates a load of each of the wheels; and a force generation section that, after judging that braking is performed in a state in which a load difference exists between left and right wheels of the vehicle based on a value that is estimated by the load estimation section, even if the pedal operation detection section detects a pedal stroke or a brake pedal force that is the same as for the braking at a time of judging or for braking prior to the judging, generates a caliper force that is different to the caliper force before the judgment.
