Method for autonoumously braking a motor vehicle and autonomous braking system for a motor vehicle

Abstract: The invention relates to a method for autonomously braking a motor vehicle (1) by means of an autonomous braking system (2) of the vehicle (1), comprising the step of detecting an obstacle (5) present in a surrounding area (6) of the vehicle (1) by means of a sensor device (7) of the vehicle (1), and the step of autonomously braking the vehicle (1) by means of the autonomous braking system (2) upon a braking criterion in respect of a distance (9) between the obstacle (5) and the vehicle (1) being fulfilled, wherein at least one braking parameter is set for the autonomous braking. A road surface parameter (µ) describing a road surface condition is determined and considered by the autonomous braking system (2) for the autonomous braking. The invention also relates to an autonomous braking system (2) for autonomously braking a vehicle (1).

Speed control and braking system

Abstract: This invention relates to braking systems and to speed control systems, and it has for an object to provide a braking or retarding effect when a predetermined speed is exceeded A further object of the invention is to obtain speed control by a differential mechanism which is operated in part

Motor control circuit

Abstract: A motor control circuit for rapidly starting and stopping a direct current motor in relation to a start-stop switch operation for energizing and de-energizing the motor is disclosed. The motor control circuit preferably includes a plurality of semiconductor switching means for controlling the power application thereto and also for applying dynamic braking thereto. The dynamic braking circuit means automatically shunts the armature of the motor for a predetermined time to be long enough to stop the motor when the start-stop switch disconnects the power thereto. The dynamic braking circuit means is energized by a separate power source for the predetermined time rather than the electromotive force generated from the motor.

Forward/backward movement switching device of electric drive type cargo handling vehicle

Abstract: PROBLEM TO BE SOLVED: To switch between forward and backward movements of an electric drive type cargo handling vehicle in a short time. SOLUTION: A forward/backward movement control part 21a provided to a traveling controller 21 for controlling traveling comprises a brake control part 25 for finding a regenerative braking torque of a regeneration brake corresponding to a traveling speed and allocating the regenerative braking torque to all braking torques at the time of switching between forward and backward movements when a traveling direction is switched to a direction opposite to a current traveling direction by a forward/backward movement switch lever, and for finding a machine braking torque of an oil hydraulic brake supplemented to the regenerative braking torque, a regenerative braking output part 27 actuating a regeneration brake based on the all braking torques or the regenerative braking torque found by the brake control part 25, and a machine braking output part 28 actuating the oil hydraulic brake based on the machine braking torque found by the brake control part 25.
