Abstract
The utility model discloses a electricelectric motor car is from seat alarm control circuit, including vehicle control unit and gear switch main part, from seat alarm control circuit main part includes vehicle control unit, pressure sensor switch, gear switch, audible-visual annunciator, wherein, pressure sensor switch output links to each other with the vehicle control unit input, and gear switch links to each other with the vehicle control unit input, and the vehicle control unit output links to each other with the audible-visual annunciator input. If the driver leaves when the seat, vehicle actuating system still is in "can travel the mode", then through an audible-visual annunciator suggestion driver, the utility model mainly provides a simple to operate, with low costs leave a warning control circuit and solve pure electric vehicles because of not leaving the unexpected problem of traveling that the warning control circuit caused because self electricity driven system caused.
Description
Technical Field
The utility model belongs to electric motor car alarm control circuit field especially relates to a electricelectric motor car is from seat alarm control circuit.
Background
According to the requirements of technical conditions for safety of motor vehicle operation (GB 7258-2017) 12.13.5: when a driver leaves a pure electric vehicle or a plug-in hybrid electric vehicle, if a vehicle driving system is still in a 'drivable mode', the driver is prompted by an obvious signal device (such as an acoustic or optical signal), and after the driver cuts off the power supply, the pure electric vehicle cannot drive undesirably due to the electric driving system of the pure electric vehicle.
However, for the pure electric vehicle in the prior art, a control circuit convenient to mount does not control the pure electric vehicle to give an off-seat alarm, and the vehicle controller does not provide two pins convenient to identify and connect for receiving and judging whether the driver sits or not and whether the pure electric vehicle is in a signal capable of driving mode or not, so that the pure electric vehicle generates an unexpected driving risk caused by an electric driving system of the electric vehicle, and the driver cannot timely learn the occurrence of the risk in advance, thereby causing the problems of personal safety or property loss and the like of the driver and other people.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the technical problem that will solve is: the utility model provides a pure electric vehicle leaves seat warning simple and easy control circuit is in order to solve among the prior art can't judge whether the driver leaves the seat, and pure electric vehicles still is in when can driving the mode at vehicle driving system, can not indicate the driver through triggering an obvious signal alarm device to lead to pure electric vehicles to produce the unexpected problem of traveling that is caused by self electric drive system.
The technical scheme of the utility model is that:
an off-seat alarm control circuit of a pure electric vehicle comprises an off-seat switch, a gear switch, an audible and visual alarm and a vehicle control unit, wherein the output end of the off-seat switch is connected with the input port of the vehicle control unit, and the output end of the gear switch is connected with the input end of the vehicle control unit; the output port of the vehicle controller is connected with the audible and visual alarm;
the seat-off switch is a pressure sensor switch which is arranged in the center of the lower surface of a cushion of the electric vehicle seat.
The utility model discloses beneficial effect:
the utility model discloses an install a pressure sensor switch in the centre below the cushion of electric motor car seat for detect the driver is in the state of sitting or the state of leaving the seat, and through high level or low level signal output to vehicle control unit, be difficult to cause the erroneous judgement; the current gear information of the electric vehicle is detected through the gear switch, a high level or low level signal is sent to the vehicle control unit, and the vehicle control unit accurately judges the gear state of the electric vehicle according to the received level signal; an audible and visual alarm is additionally arranged to prompt a driver, so that the pure electric vehicle is prevented from driving unexpectedly; the problem of the electric motor car of prior art because do not have this off-seat warning control circuit and thus the unexpected travel that causes threatens driver and other people's personal safety etc. is solved.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
As shown in fig. 1, the embodiment of the utility model discloses pure electric vehicles is from seat alarm control circuit, including pressure sensor switch 1, gear switch 2, vehicle control unit 3 and audible-visual annunciator 4, wherein, pressure sensor switch 1 output links to each other with vehicle control unit 3 input, and gear switch 2 links to each other with vehicle control unit 3 input, and vehicle control unit 3 output links to each other with audible-visual annunciator 4 input.
The utility model discloses a concrete theory of operation does:
the utility model discloses an it uses automobile-used connection of electric lines to become a whole to this off-seat alarm control circuit with pressure sensor switch, gear switch, vehicle control unit and audible-visual annunciator, wherein, installs the positive central point department below the electric motor car seat with pressure sensor switch, and vehicle control unit uses wuhan to close well power technology finite company and produces, the model: the HIE200A-1Z-HK is provided with two pins which are respectively used for judging whether a driver sits or not and controlling an audible and visual alarm to work; the audible and visual alarm is produced by Shanghai Senao electrical apparatus Limited company, and has the following model: SAD 16-16 SM, working voltage is 12V, a gear switch is carried by an electric vehicle, the model is H6-2151010EV, and the gear switch outputs signals to a vehicle control unit; when a driver sits, the pressure sensor switch is closed to output a high level, the whole vehicle controller does not react, when the driver leaves the seat, the pressure sensor switch is disconnected to output a low level, the input low level is effective at the moment, the whole vehicle controller receives a low level signal, meanwhile, if the gear is in a neutral gear, the gear switch outputs a high level signal, the whole vehicle controller does not react, if the vehicle gear is in a D-gear or R-gear drivable mode, the gear switch outputs a low level signal which is effective, at the moment, the whole vehicle controller outputs a low level signal which is effective, the audible and visual alarm is controlled to be powered on, the audible and visual alarm starts to work, the audible and visual signal is sent to prompt the driver, so that a complete control circuit is formed from judging whether the driver leaves the seat, whether the vehicle is in a drivable state, to controlling whether the audible and visual alarm is powered on, and the problem that the pure electric vehicle is not provided with an out-of-seat alarm control The problem of running.
Claims (2)
1. The utility model provides a pure electric vehicle is from seat alarm control circuit, it includes vehicle control unit and gear switch, its characterized in that: the output end of the off-seat switch is connected with the input end of the whole vehicle controller, the gear switch is connected with the input end of the whole vehicle controller, and the output end of the whole vehicle controller is connected with the input end of the audible and visual alarm.
