Abstract

The utility model discloses an electronic parking braking system with the AUTOHOLD function, which comprises an electronic parking braking (EPB) switch, an EPB controller, an instrument panel display module, an AUTOHOLD switch, EPB left rear braking callipers and EPB right rear braking callipers. The utility model effectively solves the problem that when driving on a city road, a driver needs to frequently and manually operate to park/release and also solves the problems of temperature reduction of a brake disc, reduction of parking braking power and easy slope sliding.

Description

A kind of electronic brake system with AUTOHOLD function

Technical field

The utility model relates to field of automotive braking technique, is specially a kind of electronic brake system of the AUTOHOLD of having function.

Background technology

When vehicle can run into situations such as traffic congestion, traffic lights frequently when urban highway travels, need frequent manipulation braking during standstill pull bar Parking.This has brought certain difficulty for the less chaufeur of strength.The sense tired out of chaufeur is risen behind the urban drive for a long time.Even the novel electronic emergency brake system also needs frequent manipulation braking during standstill switch, and is very loaded down with trivial details.

Traditional Pan Gu's formula emergency brake system, emergency brake system separates with service braking system, and service brake is little to the influence of braking during standstill for a long time.For the brake system of Parking and driving integral type, self-propelled vehicle is after braking for a long time, and the temperature build-up of brake disc can make the brake disc volume become big.Behind the braking during standstill, along with the temperature decline of brake disc, the volume-diminished of brake disc, the spacing between brake disc and the friction lining become big, cause braking during standstill power to descend, and the danger on slide slope takes place.

The utility model content

The purpose of this utility model provides a kind of electronic brake system of the AUTOHOLD of having function, and is frequent to solve existing emergency brake system operation, and the problem on slide slope easily takes place.

In order to achieve the above object, the technical scheme that the utility model adopted is:

A kind of electronic brake system with AUTOHOLD function, include the EPB controller, be integrated with acceleration pick-up in the described EPB controller, the signaling interface of EPB controller corresponding A UTOHOLD function powers on and is connected to the AUTOHOLD switch, it is characterized in that: the signaling interface of described EPB controller is electrically connected with the self-propelled vehicle ignition device by lead, go back electricity on the signaling interface of EPB controller corresponding A UTOHOLD function and have access to the EPB switch, the output interface of described EPB controller is by a lead and an EPB left side, the control end of right back brake caliper is electrically connected, also be electrically connected with the instrument carrier panel display module on the output interface of EPB controller, the CAN bus interface of described EPB controller has access to the CAN bus of self-propelled vehicle.

Described a kind of electronic brake system with AUTOHOLD function is characterized in that: the Parking switch and the release-push that are integrated with self-propelled vehicle in the described EPB switch.

Described a kind of electronic brake system with AUTOHOLD function is characterized in that: described instrument carrier panel display module is made of instrument carrier panel, the status indicator lamp, the buzzer phone that are integrated on the instrument carrier panel.

When the utility model has solved effectively and driven in the urban road, need the problem of the frequent manual control Parking/release of chaufeur.And the decline of brake disc temperature, braking during standstill power reduces, easily the problem on slide slope.The utility model also has following advantage simultaneously:

1, chaufeur can select whether to open the AUTOHOLD function according to driving habit.For the chaufeur of hobby use service braking system in of short duration parking, use the frequent Parking of AUTOHOLD function meeting to make the chaufeur incompatibility, therefore can select to close the AUTOHOLD function.

2, system does not need additive incrementation sensor and external circuit, only need use CAN communication can obtain various signals such as the speed of a motor vehicle, wheel speed, speed-slackening signal, engine speed, provides cost savings.

3, for driving new hand, the phenomenon of pull-up braking during standstill not after stopping appears in regular meeting.The utlity model has engine off or ignition lock and close the function of automatic parking, simplified the chaufeur driver behavior.

Description of drawings

Fig. 1 is the utility model system principle diagram.

The specific embodiment

As shown in Figure 1.A kind of electronic brake system with AUTOHOLD function comprises the right back brake caliper composition 8 of EPB switch 10, EPB controller 14, instrument carrier panel display module 12, AUTOHOLD switch 15, the left back brake caliper 7 of EPB and EPB.

Integrated Parking is opened 2 and is closed and 1 two switches of release-push in the EPB switch, and directly links to each other with EPB controller 14 by lead, and chaufeur can be controlled electronic brake system Parking or releases by Parking switch 2.

EPB controller 14 inside have the interface 11 of junctor motor-car CAN bus, acceleration pick-up 13.Be used for obtaining required data with other module communications of self-propelled vehicle.

AUTOHOLD switch 15 directly links to each other with EPB controller 14 by lead, after chaufeur is pressed switch, and EPB controller 14 On/Off AUTOHOLD functions.

The opening and closing of AUTOHOLD function 15 also can realize by the release-push of handling in the EPB switch 10 1.Open when sending ignition signal 4 at the ignition lock of ignition device, longly open or close the AUTOHOLD function by release-push 1.SELF CL AUTOHOLD function when ignition lock is closed.

The on-off signal of self-propelled vehicle ignition device directly is sent to EPB controller 14 by lead.

Instrument carrier panel display module 12 is integrated with status indicator lamp 5, buzzer phone 6, by the acousto-optic electricity will report to the police, Parking indication, discharge indication, the AUTOHOLD indication information is presented on the gauge panel and reads for chaufeur.

EPB controller 14 communicates by car load CAN bus 3 and vehicle ESP module, obtains braking and vehicle speed signal, control ESP system maintenance/release brake-pipe pressure.

After the AUTOHOLD function was opened, after chaufeur was stepped on the speed of a motor vehicle of braking and is zero, EPB controller 14 order ESP systems kept brake-pipe pressures, kept vehicle can not slip car.As if ESP system et out of order this moment, in the time of can't keeping brake-pipe pressure, EPB controller 14 control left and right sides Parking actuating units 7,8 carry out Parking.

After the self-propelled vehicle Parking, the brake disc temperature descends, and it expands with heat and contract with cold and can cause stepping up power decline, and EPB controller 14 can calculate the temperature of brake disc, and steps up once more after brake disc is cooled to a certain degree, to guarantee to do enough Parking power.

When engine off or ignition lock were closed, car was in dead ship condition, and EPB controller 14 can the Parkings of automatic guidance emergency brake system.
