Description
Technical Field
The invention belongs to the field of braking of air braking vehicles (commercial vehicles and passenger vehicles), and particularly relates to a method for automatically actuating an air braking vehicle to stop when a driver leaves a seat.
Meanwhile, the information is sent to a network platform through a remote monitoring terminal or a driving recorder and the like, and then the information is sent to a driver or a vehicle owner through the network platform. The vehicle-mounted equipment Bluetooth device can be bound with equipment such as a driver mobile phone, and the Bluetooth equipment sends information to the driver mobile phone to inform the driver of parking in an effective parking mode as soon as possible.
If the vehicle speed is lower than a certain vehicle speed, the vehicle controller ECU detects that an accelerator pedal, a brake pedal and a clutch pedal (if any) are all in a non-working state, and simultaneously detects that no person is on a driver seat, and automatically places the vehicle in a service braking state by means of a brake valve module of a vehicle EBS braking system; meanwhile, the network platform sends information or telephone notification to the vehicle owner or the driver (or the vehicle-mounted equipment is connected with the mobile phone through the Bluetooth to notify the driver) through the remote monitoring terminal or the running recorder, so that the vehicle is in a normal parking state as soon as possible.
Background
In the prior art, the air braking vehicle mainly relates to a commercial vehicle and a passenger vehicle, and some drivers are in a hurry for doing things; or a driver simply gets off the vehicle and transfers the vehicle after the vehicle stops, and neglects to place the hand brake valve at the parking brake position, at the moment, the vehicle has no any brake force, so that great hidden danger and danger are generated, and other innocent people outside the vehicle are injured or property loss is caused sometimes, so that accidents are caused.
At present, a manual valve is used in a pneumatic brake system of a special vehicle, a commercial vehicle and a passenger car as a parking brake control mode, and parking brake force is provided after spring force of a spring cavity of a spring brake air chamber is amplified. During parking, the hand brake valve cuts off the air storage cylinder to the spring cavity of the spring brake air chamber, compressed air in the spring cavity is exhausted to the atmosphere, and the parking spring pushes the piston push rod to extend out, so that the brake is driven to brake.
Due to the requirements of the national standard GB 7258-2017 item 12.13.5, the requirement is that the driver should be prompted by an obvious signal device (such as an acoustic or optical signal) when the driver leaves the pure electric vehicle or the plug-in hybrid electric vehicle and the vehicle driving system is still in the driving-capable mode. If the light gives out audible and visual alarm, sometimes the driver is not focused or the environment is noisy, so that the driver is difficult to feel. Therefore, the vehicle has the problem that the driver leaves the vehicle without adopting the parking brake, so that the vehicle slips down the slope.
Disclosure of Invention
The invention provides a method for automatically actuating air brake to stop a vehicle when a driver leaves a seat, wherein when the driver leaves the vehicle (leaves a driver seat) and forgets to brake a handle, service brake is prompted, so that the vehicle is kept in a static state, and the vehicle is ensured not to slide down a slope; on the other hand, the vehicle-mounted terminals such as the vehicle remote monitoring system send information to the network platform to inform a vehicle owner or a driver of parking, and accidents are avoided.
The concept of the invention is as follows: various signals of the vehicle are collected by the vehicle control unit, and the driver is confirmed to leave the seat through certain logic judgment, and the vehicle is in an unparked braking state, so that the service braking of the vehicle is automatically actuated, the vehicle obtains effective service braking force, and the vehicle is prevented from slipping; on the other hand, in order to avoid the power consumption of the chassis storage battery, the vehicle-mounted remote monitoring or driving recorder is controlled through bus communication or hard wires, information is sent to the network platform, and then the network platform informs a vehicle owner or a driver through short messages or a telephone.
Therefore, the technical scheme of the invention is as follows: the method for automatically actuating the air brake vehicle to stop when a driver leaves a seat specifically comprises the following steps:
a mechanical trigger switch is arranged under the driver seat; the method comprises the following steps that the existing vehicle controller, a clutch pedal sensor signal, an accelerator pedal sensor signal, a parking brake manual valve switch signal and a mechanical trigger switch signal are transmitted to the vehicle controller, and the vehicle controller controls an EBS front axle service brake module and an EBS rear axle service brake module;
(2) when the vehicle controller confirms that the hand brake valve is in a closed state, the vehicle speed is zero, the mechanical switch is released, and the accelerator pedal and the clutch brake are not trampled, the vehicle controller outputs signals to control the EBS front axle service brake module and the EBS rear axle service brake module to be opened, so that the vehicle is in a service brake state.
The technical scheme is further limited as follows: in order to avoid the problem that the air pressure of the air storage cylinder is low due to air leakage of a pipeline or the electric quantity of the storage battery is excessively consumed due to the fact that the electromagnetic valve is electrified, the vehicle-mounted remote monitoring terminal and the running recorder send information or a telephone to a vehicle owner or a driver through the network platform to inform the driver to process the parking braking problem as soon as possible.
The invention has the beneficial effects that: the invention only adds the mechanical trigger switch arranged under the driver seat, when the driver leaves the seat after stopping, and does not adopt the parking braking measure, the vehicle starts the service braking; meanwhile, the driver or the owner is informed through the network, so that the time is won for the driver to take remedial treatment measures, and accidents such as vehicle sliding and the like are reduced; the invention realizes the purpose of improving the vehicle safety by means of the prior equipment such as the prior EBS service braking system and the like under the condition of not increasing excessive cost.

Detailed Description
The invention is further described below in conjunction with the flow diagram of fig. 1: the method for automatically actuating the air brake vehicle to stop when a driver leaves a seat specifically comprises the following steps:
a mechanical trigger switch is arranged under the driver seat; the method comprises the following steps that the existing vehicle controller, a clutch pedal sensor signal, an accelerator pedal sensor signal, a parking brake manual valve switch signal and a mechanical trigger switch signal are transmitted to the vehicle controller, and the vehicle controller controls an EBS front axle service brake module and an EBS rear axle service brake module;
(2) when the vehicle controller confirms that the hand brake valve is in a closed state, the vehicle speed is zero, the mechanical switch is released, and the accelerator pedal and the clutch brake are not trampled, the vehicle controller outputs signals to control the EBS front axle service brake module and the EBS rear axle service brake module to be opened, so that the vehicle is in a service brake state.
As shown in fig. 1, in order to avoid the problem that the air pressure of the air reservoir is low due to air leakage of the pipeline or the electric quantity of the storage battery is consumed too much due to the fact that the electromagnetic valve is electrified, the vehicle-mounted remote monitoring terminal and the driving recorder (vehicle-mounted network terminal) send information or a telephone to a vehicle owner or a driver through the network platform to inform the driver to deal with the parking brake problem as soon as possible.
