Description

Technical Field

[0001] This solution belongs to the technical field of automotive safe driving, and specifically relates to a driver's bad behavior monitoring device and method. Background Art

[0002] During daily driving, accidents often occur where the accelerator is mistaken for the brake, resulting in tragic consequences. Drivers should develop the habit of moving their right foot to the brake pedal as soon as they lift their foot off the accelerator, rather than leaving it relaxed on the driver's cab floor. This can prevent the situation of not being able to find the brake in case of an emergency and mistakenly stepping on the accelerator instead of the brake.

[0003] A Chinese patent document discloses a driver's right foot movement monitoring system [Application No.: 202120120247.2]. This movement monitoring system includes a fulcrum area sensor located in the normal fulcrum area in front of the brake, a prohibited area sensor located in the prohibited area in front of the accelerator, as well as a microprocessor and a display. The fulcrum area sensor and the prohibited area sensor are respectively connected to the microprocessor through their corresponding lines, and a position determination light band connected to the microprocessor through a line is provided on the display. This position determination light band can display different set colors of light according to whether the position signal received by the microprocessor comes from the fulcrum area sensor or the prohibited area sensor.

[0004] Although the above solution can make the training of the driver's right foot movement scientific and standardized, with clear actions, standardized operations, and being assessable and verifiable, in actual driving, there is still the problem of the driver crossing their legs. Crossing legs while driving is very likely to result in being unable to react in time in case of an emergency, thus leading to tragic consequences. Therefore, there is an urgent need for a driver's bad behavior monitoring device. Summary of the Invention

[0005] The purpose of this solution is to provide a driver's bad behavior monitoring device and method to solve the problem of the driver crossing their legs.

[0006] To achieve the above purpose, this solution provides a driver's bad behavior monitoring device, including a pressure sensor and a processor arranged on the driver's cab floor. The pressure sensor is electrically connected to the processor. It also includes a spring, a metal ball, and an inductive proximity switch. One end of the spring is fixedly connected to the metal ball, and the other end is detachably connected to the driver's cab floor. Inductive proximity switches are symmetrically arranged on both sides of the metal ball, and the inductive proximity switches are electrically connected to the processor.

[0007] The principle of this solution is: the device is pre-installed on the foot pad position of the vehicle's cab. During driving, the driver normally places his feet on the pressure sensor. The pressure sensor detects two pressure points, and this is a normal driving state. If the pressure sensor detects one pressure point or three or more pressure points, it means that the driver's foot movements are not standard, or there are other objects on the pressure sensor. At this time, the processor records this bad behavior. When the vehicle turns, the metal ball will deviate in the opposite direction under the action of inertia. At this time, the sensor on the side of the metal ball's deviation direction senses the metal ball and transmits a signal to the processor, thereby judging whether the vehicle is turning left or right. At this time, the processor combines the vehicle's turn signal situation. If the turn signal direction is inconsistent with the actual turning direction, or the turn signal is not turned on when turning, the processor records this behavior. When the vehicle turns, the driver needs to step on the brakes. At this time, it is very dangerous if the driver is in a cross-legged state. Therefore, this device combines the pressure points and turning conditions to record and monitor the driver's bad behavior.

[0008] The technical effects of this solution are:

[0009] 1. By monitoring the number of pressure points detected by the pressure sensor, it can be determined whether the driver crosses his legs during driving, and whether he places debris on the floor mat of the cab, and the processor records the data to monitor such bad behavior of the driver.

[0010] 2. By setting up a metal ball, a spring and an inductive proximity switch, it can be determined whether the vehicle is in a turning state. At this time, combined with the vehicle's lighting conditions, the situation in which the driver does not turn on the turn signal or turns on the turn signal by mistake can be monitored.

[0011] 3. Crossing the legs when turning is a more dangerous behavior. This device can monitor the situation of the driver crossing his legs when turning by combining the pressure points and the deviation of the metal ball.

[0012] Furthermore, the processor is a vehicle computer system. When the signal of the pressure sensor is transmitted to the vehicle computer system, the vehicle computer system can process and record the signal according to the vehicle state; the vehicle computer system provided by the vehicle is used, and no additional processor is required.

[0013] Further, a method for monitoring driver misbehavior comprises the following steps:

[0014] Step S1: pre-install the device at the vehicle cab foot pad position;

[0015] Step S2: The driver enters the cab and starts driving;

[0016] Step S3: When the pressure sensor detects two pressure points, the processor determines that the driver is in a normal driving state at this time;

[0017] Step S4: When the pressure sensor detects only one pressure point, the processor determines that the driver is in the crossed - legs state at this time and records this bad behavior of the driver.

[0018] Step S5: When the pressure sensor detects three or more pressure points, the processor determines that there are other items on the pressure sensor at this time. If the driver still does not remove the item after exceeding the set duration, then this bad behavior of the driver is recorded.

[0019] The principle of this method is as follows: This device is pre - installed on the vehicle. As long as the driver's foot is placed on the driver's cab floor mat position, the number of pressure points can be detected. The normal state is two pressure points. When there is one pressure point or multiple pressure points, it means that the driver is in the crossed - legs state or there are other items placed on the pressure sensor. In either case, it may affect driving.

[0020] The beneficial effect of this method is that by detecting the number of pressure points, the processor can convert it into signals of different driving states of the driver, and record the situation of crossing legs or placing other items on the pressure sensor into the system, realizing real - time monitoring of the driver's bad behaviors.

[0021] Furthermore, in step S3, although the pressure sensor detects two pressure points, when one of the pressure points does not change for more than the set duration, the processor determines that the driver is in the crossed - legs state at this time and records this bad behavior of the driver. During driving, if the driver's foot remains in one position for a long time, it is easy to get numb. Normally, the driver will adjust the posture appropriately every once in a while, and at this time the pressure points will change; if the pressure points do not change for a long time, it may be that the driver, in order to avoid monitoring, places a heavy object on the pressure sensor while crossing legs. Normally, the heavy object does not change. The set duration of this device can effectively avoid this situation.

[0022] Furthermore, when the pressure sensor detects two pressure points, when the metal ball touches the pressure sensor, the processor determines that the vehicle is passing through a bumpy section, and the set duration starts over. When the vehicle passes through a bumpy section, there will be intermittent separation between the driver's feet and the pressure sensor. When the feet are separated, the metal ball touches the pressure sensor to form a pressure point. At this time, it belongs to the normal driving state, and the driver's feet are relaxed when leaving the pressure sensor. When the feet return to the sensor again, they may move after a while; recalculating the set duration can avoid misjudging the driver's normal driving state as crossing legs after passing through a bumpy section, thus resulting in inaccurate monitoring data.

[0024] Figure 2Schematic flowchart of the driver's bad behavior monitoring method according to an embodiment of the present invention. Detailed implementation manners

[0025] The following is a further detailed description through specific implementation manners:

[0026] The reference numerals in the accompanying drawings of the specification include: pressure sensor 1, inductive proximity switch 2, metal ball 3, and spring 4.

[0027] The embodiment is basically as shown in the Figure 1 accompanying drawings:

[0028] A driver's bad behavior monitoring device mainly consists of a pressure sensor 1 and a processor. The pressure sensor 1 is set to have the same shape as the driver's cab floor mat, and the processor is set to be a vehicle-mounted system. The pressure sensor 1 is electrically connected to the vehicle-mounted system, and the pressure signal detected by the pressure sensor 1 is directly transmitted to the vehicle-mounted system for processing by the vehicle-mounted system. Specifically, a spring 4, a metal ball 3, and an inductive proximity switch 2 are also provided. One end of the spring 4 is fixedly connected to the metal ball 3, which can be specifically welded or thread-connected, and the other end is detachably connected to the cab floor during installation, which can be specifically thread-connected; the inductive proximity switches 2 are symmetrically arranged on both sides of the metal ball 3 and are fixedly installed on this device; the inductive proximity switch 2 is electrically connected to the processor.

[0029] During actual operation, pre-install this device under the driver's cab floor mat, and set a preset duration on the in-vehicle system. The specific duration is obtained by measuring the duration during which the pressure points do not change during actual driving. After measuring multiple groups of data, the average value is 8 minutes. Considering the situation where some drivers have a relatively long interval between foot movements, the preset duration is set to 10 minutes. During specific implementation, the preset duration can be adjusted according to individual differences of the driver. At the same time, ensure that this device is on the same horizontal plane as the cab floor and there are no protrusions. When the driver enters the cab and starts driving, place both feet on the pressure sensor 1. At this time, the pressure sensor 1 detects two pressure points, and the in-vehicle system determines that the driver's foot behavior is normal at this time. However, to rule out the situation where the driver crosses one leg and places an object on the pressure sensor 1 at the same time, when the pressure points do not change for more than the preset time, the processor determines that the driver is crossing one leg and placing sundries on this device at this time, and records this bad behavior. In addition, when the vehicle passes through a bumpy section, the driver's feet will intermittently leave the pressure sensor 1 as the vehicle jolts, and at the same time the metal ball 3 will contact the pressure sensor 1. Specifically, the pressure sensor 1 is a double-sided sensor. When the side of the pressure sensor 1 close to the ground contacts the metal ball 3, at this time the processor determines that the vehicle has passed through a bumpy section and the driver is in a normal driving state, and recalculates the preset duration. When the pressure sensor 1 detects only one pressure point, at this time the processor determines that the driver is in a state of crossing one leg and records this behavior. When the pressure sensor 1 detects three or more pressure points, the processor determines that there are other objects on the pressure sensor 1. If they are not cleared after exceeding the preset duration, this behavior is recorded.

[0030] When the vehicle turns left, due to the inertial effect, the spring 4 will deform to the right, and then drive the metal ball 3 on the spring 4 to shift to the right. At this time, the right inductive proximity switch 2 senses the metal ball 3 and sends a left-turn signal to the processor. The processor combines the situation of the vehicle turning on the turn signal. If the vehicle does not turn on the turn signal or turns on the right turn signal, the behavior of the vehicle turning on the turn signal incorrectly at this time is recorded. If the turn signal situation is consistent with the turning situation, it is not recorded; conversely, turning right is the same as turning left.

[0031] As attached Figure 2 shown:

[0032] A method for monitoring drivers' bad behaviors is also disclosed, including the following steps:

[0033] Step S1: Pre-install this device at the position of the driver's cab floor mat;

[0034] Step S2: The driver enters the cab and starts driving;

[0035] Step S3: When the pressure sensor 1 detects two pressure points, the processor determines that the driver is in a normal driving state at this time; if the pressure sensor detects two pressure points, but one of the pressure points remains unchanged for more than the set duration, the processor determines that the driver is in a crossed-legs state at this time and records this bad behavior of the driver; when the pressure sensor detects two pressure points and the metal ball touches the pressure sensor, the processor determines that the vehicle is passing through a bumpy section and the set duration starts over.

[0036] Step S4: When the pressure sensor 1 detects only one pressure point, the processor determines that the driver is in a crossed-legs state at this time and records this bad behavior of the driver.

[0037] Step S5: When the pressure sensor 1 detects three or more pressure points, the processor determines that the driver has placed other items at the position of the driver's cab foot mat and records this bad behavior of the driver.

[0038] Compared with the existing driver bad behavior monitoring device, the present invention effectively solves the problem of the driver crossing their legs during driving.

[0039] The above are only embodiments of the present invention, and common knowledge such as the specific structure and characteristics known in the solution is not described in detail here. It should be noted that for those skilled in the art, without departing from the structure of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent. The protection scope required by this application should be based on the content of its claims, and the specific implementation manners described in the specification can be used to explain the content of the claims.
