Abstract: A method and a device for controlling the brake system of a vehicle, wherein a stand-by phase is made available. The stand-by phase is initiated as soon as the input pressure exceeds a threshold value S1 and the rate of change of input pressure exceeds a third threshold value SB. The third threshold value SB is smaller than a second threshold value S2, which when exceeded immediately changes the braking operation into a full braking support operation. When the third threshold value SB is exceeded or when the stand-by phase is entered, the brake support system is activated or becomes ready to use, however, a full braking support operation is not triggered yet. During the stand-by phase, the braking behavior of the driver is continually monitored.

Abstract: A vehicle deceleration force control device of the invention reduces deceleration force (assist braking force) during implementation of engine brake assist control over a predetermined time (t2-t0) when a vehicle state is changed to an acceleration state by operation of an accelerator. A change amount of the deceleration force over time during reduction is limited to a predetermined value or less. This predetermined value is set to a larger value the steeper the road gradient during hill descent and is set to a smaller value the steeper the road gradient during hill climbing. The vehicle deceleration force control device enables smooth acceleration when shifting from deceleration to acceleration.

Abstract: An enhanced emergency brake assist system includes an accelerator pedal operated by the driver coupled to a braking system and used to control the overall vehicle speed. When a forward detection apparatus detects an imminent contact, the braking system automatically applies braking force to the vehicle after the driver fully releases the accelerator pedal. The braking force may be reduced when the driver or passenger are unbuckled.

Abstract: A vehicle brake control device includes a brake member, a wheel brake cylinder mounted on a wheel, and a master cylinder. The master cylinder generates a master cylinder hydraulic pressure in response to an operating force applied to the brake member. The brake control device also includes an automatic pressure increasing control device, a braking force control device, a coefficient of friction detecting device that detects a coefficient of friction of the road, and an automatic pressure increasing restraining device. The automatic pressure increasing control device controls automatic pressure increasing operation of the master cylinder based on the operating force applied to the brake member. The braking force control device controls the increased master cylinder hydraulic pressure supplied to the wheel brake cylinder. The automatic pressure increasing restraining device restrains automatic pressure increasing operation of the master cylinder when anti-skid control is being performed with a low coefficient of friction.

Abstract: A brake control apparatus for a vehicle employs a pressure-amplifying device which reduces a quantity of brake fluid generating a first brake-fluid pressure in a first conduit connected to a master cylinder, and increases second brake-fluid pressure in a second conduit, applied to a wheel cylinder simultaneously with the reduction in brake-fluid quantity in the first conduit. As a result, increase in the first brake-fluid pressure is suppressed even when a driver depress a brake pedal and load to generate the first brake-fluid pressure is alleviated. Additionally, the pressure-amplifying device applies the increased second brake-fluid pressure to the wheel cylinder. Therefore, it is possible to ensure sufficient braking force.

Abstract: To properly improve safety of a straddle-type vehicle.
The controller includes a determination unit and an execution unit. The determination unit (63) determines, based on at least one of a first master cylinder pressure and a second master cylinder pressure, whether a braking operation is performed. The execution unit executes a driving support mode, in which a braking force generated in a straddle-type vehicle is amplified, when the determination unit determines that the braking operation is performed. The execution unit, in the driving support mode, amplifies: the braking force generated in the straddle-type vehicle, based on surrounding environment information about environment around the straddle-type vehicle; the braking force generated in the straddle-type vehicle with the amplification of the second wheel cylinder pressure superior to the amplification of the first wheel cylinder pressure when the rider performs the braking operation with the operation of the first braking operation unit superior to the operation of the second braking operation unit; and the braking force generated in the straddle-type vehicle with the amplification of the first wheel cylinder pressure superior to the amplification of the second wheel cylinder pressure when the rider performs the braking operation with the operation of the second braking operation unit superior to the operation of the first braking operation unit.

Abstract: A system and method are provided for estimating progression in vehicle tire wear. A tread depth is stored at a first (e.g., initial or unworn) stage for a given tire, along with a first set of modal frequencies for the tire. At a later (e.g., worn) stage, for example in concert with a controlled excitation of tire structural modes, a second set of corresponding modal frequencies are sensed for the tire, and a tire wear status of the tire is determined at the second stage based on a calculated frequency shift between at least one corresponding modal frequency from each of the first and second sets. In one example, an initial mass of the tire is stored, and a change in mass is calculated based on the calculated frequency shift. Alternatively, a correlation of modal frequency shift may be performed with respect to tread depth for a given tire.
