Принадлежит: ROBERT BOSCH GMBH

A method for reducing the steering torque in a motor vehicle in a driving situation in which the vehicle is being braked and steered at the same time. By shifting the brake force to the rear wheels, the front wheels become easier to steer compared to a standard brake force distribution. The maximum required power of an electric steering assistance system is thus greatly reduced.

MULTIPLE-STAGE COLLISION AVOIDANCE BRAKING SYSTEM AND METHOD

Номер: US20190077384A1
Автор: GOMES ARNALDO C.
Принадлежит:

An apparatus and method for automatic actuation and control of an air braking system on a commercial vehicle, under a warning of collision conditions, has multiple stages of operation, which supplements the normal brake pedal activation and control of the air brake operation under the driver's foot control. Automatic actuation has two stages: (1) impending collision automatic activation and control for 1.4 second closure; and (2) imminent collision automatic activation and control for 0.9 seconds closure. A determination of closure occurring in excess of 1.6 seconds, turns off the warning, and also deactivates the automatic activation and control. A modification to a standard air brake system structure enables the addition of the automatic activation and control stages. When an impending collision signal is received, an activation component operates valves to pressurize the rear brakes to 40 psi. When the air pressure at the rear brakes rises to 20 psi, other valves pressurize the front brakes. This first stage automatic operation stops or slows the vehicle with 40 psi on the rear brakes and 20 psi on the front brakes. When an imminent collision signal is received, the activation component opens valves to pressurize the rear brakes to 120 psi. Once the air pressure at the rear brakes rises to 20 psi, the front brakes are also pressurized. This second stage automatic operation stops the vehicle with 120 psi on the rear brakes and 80 psi on the front brakes, unless restricted to a lower pressure by the brake system manufacturer. The driver can deactivate the automatic braking functions by stepping on the brake pedal or by operating the vehicle turn signals. 1. A method of automatic braking , collision avoidance for vehicle air brake systems , including the steps of:detecting an impending collision condition;pressurizing the rear brakes with a source pressure of about 40 psi when said impending collision condition is detected;pressurizing the front brakes when the ...

A smart braking system for a vehicle is provided. The smart braking system selectively activates a braking system of the vehicle when the smart braking system detects a scenario in which it is likely that a constant vehicle speed, rather than an increasing vehicle speed, would be desired by a driver. In one example, a driver releases an accelerator while the vehicle is on a decline but the vehicle accelerates anyway. In this instance, the smart braking system records the speed of the vehicle when the accelerator is released and applies the braking system to maintain the speed of the vehicle at the recorded speed while the vehicle is on the decline.

A vehicle control apparatus includes a controller configured to change a ratio between a regenerative braking force and a frictional braking force, in a specific wheel among wheels, such that the ratio in the specific wheel differs from the ratio between the regenerative braking force and the frictional braking force in each of the other wheels, when a command to generate the require braking force is issued and a vehicle motion control is executed. 1. A vehicle control apparatus comprising:braking-driving force generation mechanisms provided at respective wheels of a vehicle, each of the braking-driving force generation mechanisms configured to generate a driving force to be applied to a corresponding one of the wheels or a regenerative braking force to be applied to the corresponding one of the wheels;friction braking mechanisms provided at the respective wheels, each of the friction braking mechanisms configured to apply a frictional braking force to a corresponding one of the wheels; anda controller configured to control the braking-driving force generation mechanisms and the friction braking mechanisms, wherein calculate a required braking force;', 'calculate a ratio between the regenerative braking force and the frictional braking force in the required braking force to be applied to each of the wheels, based on the required braking force;', 'calculate a vehicle motion control force for causing each of the braking-driving force generation mechanisms to generate the driving force or the regenerative braking force, the vehicle motion control force being a control force for executing vehicle motion control for controlling a motion of the vehicle; and', 'change the ratio between the regenerative braking force and the frictional braking force, in a specific wheel among the wheels, such that the ratio in the specific wheel differs from the ratio between the regenerative braking force and the frictional braking force in each of the other wheels, when a command to ...
