Automatic braking system for vehicles

Abstract: The automatic braking system includes a forward looking radar system (20) that provides early warning detection of objects that call for braking action. The radar is coupled to a microprocessor based management controller (10). On the basis of parameters such as distance and rates of change, a controlled braking force is applied. The controller determines when a stop condition is achieved and the braking action is removed.

Work machine having a drive train with an enhanced engine braking mode

Abstract: An enhanced braking mode for a work machine includes activating engine compression release brakes while placing a torque converter in an overspeed condition. By doing so, both the engine and the torque converter contribute to decelerating the work machine. This combined braking horsepower is greater than that available using the engine compression release brakes with the torque converter in a locked condition. In addition, the braking horsepower available in this enhanced braking mode is comparable to that available with the employment of hydraulic retarders, which can be substantially more expensive, and require additional hydraulic cooling system capability. The enhanced braking mode is preferably carried out automatically by the electronic control module when the vehicle is in a retarding mode.

Regenerative control device and regenerative control method and hybrid motor vehicle

Abstract: A regenerative control capable of realizing a comfortable operation, along with an efficient collection of a regenerative energy of a motor generator and an effective regenerative braking control. A regenerative control device for a motor generator generates a regenerative braking power for decelerating a motor vehicle at a time of collecting regenerative energy generated by driving of the motor vehicle. The arrangement includes a driving state detection unit for detecting a driving state and a deceleration level acquisition unit for acquiring a deceleration level. A braking force setting unit sets the regenerative braking force of the motor generator at a time of detection of a deceleration operation by the driving state detection unit. A braking force adjustment unit adjusts and suppresses the regenerative braking force set by the braking force setting unit, according to acquired deceleration level.

Method and device for adjusting the braking force of the wheels of a vehicle

Abstract: Four independent braking setpoints are determined for the four wheels of the vehicle determined by a braking distribution law taking into account the deceleration setpoint (ΔLp) provided by the driver and the dynamic state of the vehicle, and the wheels of the vehicle are applied four braking torques (Cic) determined from said four braking instructions, an anti-lock braking law and a transverse stability control law.

Braking force control device for vehicle

Abstract: A braking force control apparatus for a vehicle estimates the friction coefficient µ of a road surface as the state of the road surface on which the vehicle travels, and determines (computes) an ideal braking force µW (target braking force) by making use of the estimated road surface friction coefficient µ. When the estimated road surface friction coefficient µ is equal to or greater than a predetermined friction coefficient µ0, the braking force control apparatus operates an in-wheel motor (electrical force generation mechanism) in a regeneration state to thereby generate a motor braking torque Tmr, and causes a friction brake mechanism (braking force generation mechanism) to generate a frictional braking force Bf computed by subtracting the motor braking torque Tmr from the ideal braking force µW. Meanwhile, when the estimated road surface friction coefficient µ is less than the predetermined friction coefficient µ0, the braking force control apparatus operates the in-wheel motor (electrical force generation mechanism) in a power running state to thereby generate a motor driving torque Tmc, and causes the friction brake mechanism (braking force generation mechanism) to generate a frictional braking force Bf computed by adding the motor driving torque Tmc to the ideal braking force µW.
