Battery-driven car is ridden checking device and method

Technical field

The present invention is about a kind of safety guard of battery-driven car, and whether espespecially a kind of driver of detecting has ridden on the checking device on battery-driven car.

Background technology

Be different from the motor bike that tradition uses fuel oil, the propulsion source of battery-driven car comes from storage battery, and give motor by storage battery supply electric power and produce power, under the prerequisite not needing use internal combustion engine, the noise that battery-driven car produces reduces many relatively.If surrounding environment has the disturbing influence coming from the background noises such as other on-road vehicle, most user or pedestrian almost cannot perceive the sound that battery-driven car produces, battery-driven car almost presents silent state, and this characteristic is one of advantage of bragging about of brute force all the time.

But above-mentioned battery-driven car is quiet, the characteristic of low noise also can bring the drawback of reverse side under some situation.Such as battery-driven car is by traveling through pedestrian side, and pedestrian cannot perceive battery-driven car in advance and arrives and do not dodge in advance, probably side swipe accident occurs; Such as driver starts Vehicle Power in advance again, but because present quiet noiseless state without engine, when also not riding on vehicle, easily leading false touch oil door handle in car process because not adding attention, driver not yet prepares completely namely to produce vehicle moment quick-fried punching, damages.

Although the safety guard-safeguard design of the existing part of existing battery-driven car, such as side stand cut-off switch, cradle cut-off switch etc., not yet have and judge whether driver has driven the relevant safety method on battery-driven car, really to be improved.

Summary of the invention

Because the shortcoming of prior art, the battery-driven car that main purpose of the present invention is to provide, and whether a kind of seat cushion judging battery-driven car has personnel to take is ridden checking device, can forbid that motor operation is to avoid vehicle collision that meets accident because false touch is dynamic when taking without personnel.

For reaching aforementioned object, battery-driven car of the present invention checking device of riding includes:

One sense switch group, it is the seat cushion interior being arranged at battery-driven car, and be electrically connected to an operating power, wherein, this operating power has one and detects level, this sense switch group changes its ON/OFF state according to the pressure applied on cushion, and this sense switch group can be transmitted this when conducting state and detect level;

One controller, is this sense switch group of electrical connection, and starts timing not obtaining when this detects level, detect level, interrupt the power supply of the motor of this battery-driven car when timing reaches a preset time value and continues not receive this.

This sense switch group being arranged at seat cushion interior can be reacted and be rided on battery-driven car with or without personnel, this sense switch group becomes off state without during external pressure on cushion, therefore namely this controller cannot receive this via sense switch group and detect level, now this controller starts timing, reach a Preset Time through timing and continue not receive this and detect level, namely determine that nobody rides on seat cushion, therefore interrupt providing the electric power giving motor, forbid motor operation, cause unexpected collision to avoid vehicle because of user's maloperation.

Detailed description of the invention

Please refer to shown in Fig. 1, Fig. 2, is circuit block diagram of the present invention, is to include a sense switch group 10 and a coupled controller 20.

This sense switch group 10 is seat cushion 100 inside being arranged on battery-driven car, and between the input end being connected electrically in an operating power 30 and this controller 20, wherein this operating power 30 can provide a level, such as a positive voltage level (as+VCC) or a ground connection level (GND).

This sense switch group 10 is made up of the pressure switch of at least one, can change the ON/OFF state of itself when being subject to an external pressure, and such as transfer conducting state when being under pressure to by open circuit originally, vice versa.In the following description, transfer conducting state to by open circuit originally when pressure switch is and is under pressure to illustrate as example.This sense switch group 10 can be the pressure switch of, or the pressure switch of a pair, or multipair pressure switch; Please refer to shown in Fig. 2, when pressure switch A, the B by a pair forms, the position of this pressure switch A, B corresponds to position when driver rides in seat cushion 100, personnel whether are had to ride on battery-driven car with detecting, wherein, when two pressure switch A, B all pressurized conducting time this can be detected level and be sent to this controller 20; Please refer to again shown in Fig. 3, when being made up of multipair pressure switch A1 ~ A4, B1 ~ B4, seat cushion 100 both sides can be evenly distributed in couples to provide more large-area pressure detection, this can be detected level when all there is arbitrary pressure switch conducting both sides and be sent to this controller 20, such as, after pressure switch A1 and the conducting of pressure switch B2 pressurized, can be transmitted this and detect level to controller 20.

The independent control that this controller 20 can be made up of the electronic control unit of vehicle itself (ECU) or be connected with this electronic control unit (ECU).This controller 20 comprises junction circuit 21, timekeeping circuit 22 and an output circuit 23, and wherein, this junction circuit 21 connects this sense switch group 10, judged whether that receiving this detects level; This timekeeping circuit 22 connects this junction circuit 21, detects level and namely start timing, reach after a preset time value (as 5 seconds) export a ct-off signal through timing when this junction circuit 21 does not receive this; This output circuit 23 is the power supplies controlling vehicle motor, and connects this timekeeping circuit 22, when output circuit 23 receives this ct-off signal, namely interrupts for the electric power giving motor, the motor of battery-driven car cannot be started.

About the judgement flow process of this controller 20, can with reference to shown in figure 4, this junction circuit continues detecting (S40) and whether receives this detect level to detect; Judge the whether conducting (S41) of sense switch group, if receive this to detect level, then representing on seat cushion has personnel take and can give motor (S42) by supply regular power, if do not receive this to detect level, then represent and seat cushion likely there is no personnel take, then start this timekeeping circuit 22 and start timing; And judge whether timing exceedes preset time value (S43), if have not exceeded this preset time value, then still can give motor (S42) by supply regular power, otherwise, if when exceeding this preset time value, can conclude and seat cushion is taken without personnel, namely interrupt the power supply (S44) of motor, motor is decommissioned.

When the chronograph mechanism of the invention described above is mainly in order to prevent that driver is of short duration leaves seat cushion, vehicle power-off immediately without driver judged by accident by controller 20.Such as, driver is at the parting of the ways because temporarily stopping during red light driving, and moving body and the of short duration seat cushion that leaves slightly, if controller will cut off the power supply of motor immediately without this chronograph mechanism, vehicle is decommissioned instantaneously, probably can cause unexpected generation thus, if add chronograph mechanism can avoid this kind of problem.

In sum, whether the seat cushion that the present invention can judge battery-driven car has driver to take, and when determining that nobody takes, namely interrupt delivery gives the electric power of motor.Therefore, even if driver is leading careless false touch oil door handle in car process, the problem of sudden and violent punching to lose control of one's vehicle also can not there is, for car user scholar provides better safety control.
