Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, a first embodiment of the present invention provides an EPB automatic release control method, including the following steps:
s1, judging whether a driver control vehicle exists in the vehicle or not according to the driver seat image shot by the camera or the door information of the driver seat; when the driver seat image shot by the camera is detected to comprise human body features, judging that a driver control vehicle exists in the vehicle; when the door of a driver seat is detected to be in a closed state and an operation signal of the driver exists, judging that the driver control vehicle exists in the vehicle;
when the camera is installed in the vehicle and the camera is in normal use, a driver seat image shot by the camera is obtained, and when the driver seat image comprises human body characteristics (such as ears, hairs, eyes and the characteristics of the whole head), the existence of a driver control vehicle in the vehicle is judged. On the contrary, when the driver seat image does not include the human body features, it is judged that the driver does not control the vehicle in the vehicle, and the automatic EPB releasing function cannot be started at this time, so that the vehicle cannot be out of control to cause damage to people or articles.
For a vehicle without a camera device, or when the camera cannot work normally, the system needs to adopt another effective way to determine whether a driver controlled vehicle exists in the vehicle, in this embodiment, it is determined whether the driver is in the driving position by detecting whether the door is closed + whether an operation signal of the driver exists. The operation signal of the driver is a dynamically changing signal, for example, the latch of the door is changed from unlocked to locked, and the wiper is changed from closed to open. Compared with the prior art, the prior art only judges whether the driver is in the driver seat by using the state (for example, whether the safety belt is in a fastening state), and the invention judges whether the driver is in the driver seat by using the state change (for example, the state change from the safety fastening state to the fastening state), so that whether the driver controls the vehicle can be reflected more accurately, and the problem of runaway caused by EPB false release is reduced.
Preferably, the judging whether the operation signal of the driver exists is specifically as follows:
whether the state of the vehicle is changed or not is judged through the state machine to determine whether an operation signal of a driver exists or not.
The state machine is composed of a state register and a combinational logic circuit, and can perform state transition according to a preset state according to a control signal.
Further, the operation signal of the driver includes a hand operation signal and/or a foot operation signal. The hand operation signal comprises one or more of a safety belt operation signal, a gear operation signal, an EPB operation signal, a wiper operation signal, a rearview mirror operation signal, a horn operation signal, a vehicle door locking operation signal and a vehicle window locking operation; the foot operation signal comprises an accelerator pedal operation signal and/or a brake pedal operation signal. For an automatic transmission automobile, N (neutral), R (reverse), P (park) and D (drive) are included, respectively. The N gear is a neutral gear, is used as a neutral gear of a manual gear, and is used during temporary parking. The other function is that when the engine suddenly stops during running, if the engine needs to be restarted during running, the N gear needs to be shifted. The P gear and the parking gear are used when the automobile is parked in a flameout mode or the automobile is static, and when the automobile stops, the power can be cut off, a key can be pulled out, and the automobile door can be locked only by putting the gear into the P gear. When the shift position is shifted to the P position, the brake device of the vehicle is locked, and the vehicle does not displace even when parked on a slope. The reverse gear of the manual gear has the same function as the reverse gear of the R gear. Before the R gear is engaged, it is necessary to confirm that the vehicle has stopped, and if the vehicle is not yet stable, the R gear is engaged, which may damage the transmission, and many manufacturers design misoperation-preventing buttons or positions for the purpose. The D gear, the forward gear, is used on a common road surface and is one of the most commonly used gears. The system can automatically switch to a comfortable working state according to the road condition and the speed of the automobile. For the judgment process of the EPB automatic release, the EPB automatic release is generally performed only when the other gears are shifted to the R gear or the D gear, and the shift to the other gears is also within the protection scope of the present invention.
It should be noted that the operation signal of the driver herein may be detected in real time, or after the first operation signal is detected after the door is closed, no other operation signal is detected, and after the door is opened again, the operation signal is reset or reset again, and the operation signal is detected again when waiting for the next door closing.
When the operation signal of the driver includes a hand operation signal, the determining, by the state machine, whether the state of the vehicle changes to determine whether there is an operation signal of the driver includes:
determining that an operation signal of a driver exists when it is detected that a seat belt of the driver seat is fastened by unfastening or is fastened by unfastening;
when the change of the vehicle gear is detected, determining that an operation signal of a driver exists; for example, when it is detected that the vehicle gear is shifted from any gear to a drive gear or a reverse gear, it is determined that the operation signal of the driver is present.
When the manual pull-up or release of the EPB switch is detected, it is determined that the operation signal of the driver is present.
Besides, there is a case where the driver controls the vehicle from running to stopping, the vehicle is in a parking state; however, when the driver needs to restart the vehicle, the speed of the vehicle in the driving stage can also be obtained, and when the speed of the vehicle is greater than the preset first threshold value, it is proved that the driver still operates the vehicle, that is, it is determined that the operation signal of the driver exists.
And S2, when judging that the driver control vehicle exists in the vehicle and the EPB release condition is met, controlling the EPB to release.
In step S2, the EPB release condition includes that the stepping depth of the accelerator pedal is greater than a preset second threshold, the EPB switch is in a non-manual pull-up state, the power state is in a discharging state, the vehicle gear is in a driving gear or a reverse gear, and the output power of the vehicle meets the requirement of the slope on which the vehicle is located. It should be noted that the second threshold may be zero, and that the EPB release may also be triggered by determining that the accelerator pedal is pressed. In addition, when the EPB switch is being pulled up by the driver, the driver's intention is to park, and the system cannot turn on the EPB auto release against the driver's driving intention. And further, judging whether the output power of the vehicle meets the requirements of the slope, needing to acquire the slope information of the slope sensor for calculation, and automatically releasing the EPB after the engine reaches enough power when the output power of the vehicle prevents the vehicle from sliding down the slope.
Based on the scheme that above-mentioned provided, directly acquire the portrait through the camera, perhaps through door information + driver's operating signal, can accurately judge whether the driver is located the driver seat to send the EPB release control signal who accords with actual conditions and driver actual intention, guarantee vehicle and personnel safety, and improve vehicle driving's intelligent experience.
