Booster and brake apparatus using the same

Номер: US20120200147A1

Автор: Hiroshi Owada, Mitsuhiro Endo

Принадлежит: HITACHI AUTOMOTIVE SYSTEMS LTD

An input rod is operated by a brake pedal to introduce the air into a variable-pressure chamber through a control valve to propel a power piston, thereby advancing a primary piston to generate a brake fluid pressure in a master cylinder. A part of the reaction force from the fluid pressure is transmitted to the input rod through a reaction member. The primary piston is provided with an idle stroke in which no fluid pressure is generated, and the reaction force to be transmitted to a plunger is limited by a reaction force adjusting spring. In the region of the idle stroke, a fluid pressure is supplied to a wheel cylinder through a fluid pressure control unit to perform regenerative cooperative control, and a reaction force from a reaction spring is applied to the input rod.

An electrically-driven mining vehicle includes an obstacle detector, a speed detector, and an alarm. The alarm outputs a first warning, which urges an operator of the electrically-driven mining vehicle to operate a regenerative brake pedal that actuates only the regenerative brake device, and a second warning, which urges the operator to operate a cooperative brake pedal that uses the regenerative brake device and the mechanical brake device in combination. If the travel speed of the vehicle is included in a low speed range in which no difference can be considered to exist in distance between a first braking distance upon actuation of only the regenerative brake device and a second braking distance upon operation of a cooperative braking, a signal for performing the first warning is outputted earlier by at least a warning time interval.

Hybrid Vehicle Brake Control

Номер: US20200079219A1

Автор: Dale Scott Crombez, Shunsuke Okubo

Принадлежит: FORD GLOBAL TECHNOLOGIES LLC

In a hybrid vehicle, brake force is divided between friction brakes and regenerative braking. When the friction brakes are wet, the delivered braking force may exceed the commanded braking force resulting in a poor transition from regenerative braking to friction braking. When wet friction brakes are detected, a controller allocates more of the total braking energy to friction brakes until a threshold quantity of energy has been dissipated in the friction brakes, thus drying the friction brakes over fewer braking events than otherwise.

Method and Apparatus for Recovering Energy Wheel

Принадлежит: ReWheel, Inc.

While the concept of saving automobile's intake of fuel or electricity by converting kinetic energy of an automobile into some form of potential energy, usually either electrical potential or compressed gas potential, in order to later convert that energy back into kinetic energy, has been well recognised over the years, and while the number of regenerative braking techniques and devices have been introduced over the years, with the exception of an electrical engine/generator, these techniques have not been well adapted. That was caused in part by either not a very simple implementation of those devices or by a necessity to completely re-engineer automobile powertrain in order to use those techniques. Present invention introduces a method of regenerative braking where no components of an automobile are to be replaced or removed and none of their functionality is modified. The new component described here is implemented as an additional, one piece, complete device, placed onto the existing automobile wheel's hub, and covered by the automobile's wheel. This method of regenerative braking is therefore applicable to all the automobiles, independent of their power source, to newly built automobiles and the automobiles already on the road. 1.

Принадлежит: Continental Automotive GmbH

A method for heating the interior of a motor vehicle and a heating system are described. In the method, electrical energy stored or generated in the motor vehicle or electrical energy fed from an external energy source is fed to an electrothermal transducer and is converted there to thermal energy, which is supplied to a carrier medium for the thermal energy. An electrothermal transducer is used, which is temporarily operated at a higher heating power in the heating-up phase than in the subsequent continuous operation. In this way, the motor vehicle interior is heated up significantly quicker than in the known methods.
