摘要： Acoustic medium of ultrasonic grip system consists of piezoelectric generator (1), wheel knuckle (9), ball bearing (10), wheel hub (11), wheel rim (15) and tyre of motor-car (20). The piezoelectric generator (1) creates ultrasound vibrations which are transferred through the acoustic medium to the surface of tyre (17). The ultrasound vibration on the surface of tyre (17) results in the separation of the surface of tyre (17) from the liquid (18) that may be found on tarmac (19) during the rain, which results in the fact that despite the unfavourable weather conditions the motor-car has an optimum rolling surface of tarmac. Also, the vibrations on the surface of tyre (17) in interaction with micro texture of tarmac increases the contact surface of tyre with tarmac, which results in the increase of coefficient of friction, higher grip of tyre and reduction of braking distance of motor-car. The ultrasonic grip system is activated at sudden braking, resp. activation of ABS system. Also, the system is activated on the occasion of activating the ESP and ASR system.

摘要： A method for estimating a tire property of a vehicle based on tire-to-road friction properties for a fleet of vehicles. The method includes: determining a tire-to-road friction for a plurality of vehicles, belonging to the fleet of vehicles, at a plurality of specified locations; determining a reference tire-to-road friction for the fleet of vehicles at each specified location; in a vehicle, determining a current tire-to-road friction at a first location being one of the specified locations; determining a difference between the current tire-to-road friction and the reference tire-to-road friction of the fleet for the first location; and estimating a tire property of the vehicle based on the determined difference. There is also provided a system configured to perform the described method.

摘要： The invention is concerned with the rapid release of frictional force which is acting to reduce relative movement between contacting surfaces, the normal actuating means being unaffected. One application is in an anti-lock braking system in vehicles, particularly motorcycles. A sensor monitors wheel angular velocity and when this falls below a predetermined value the sensor causes ultrasonic vibrations to be applied to brake pads effectively reducing friction without release of brake operating pressure to enable resumption of normal rotation.The invention can also be applied to friction clutches operating in either rotary or linear senses to cause release when overloading, overspeed, etc. occurs.
摘要翻译：本发明涉及摩擦力的快速释放，其作用是减小接触表面之间的相对运动，正常致动装置不受影响。一种应用是车辆中的防抱死制动系统，特别是摩托车。传感器监测车轮角速度，当该速度低于预定值时，传感器将超声波振动施加到刹车片上，有效地减少摩擦而不释放制动操作压力，以恢复正常旋转。本发明还可以应用于以旋转或线性感测操作的摩擦离合器，以在发生超载，超速等时引起释放。
