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.
The present invention provides a control device for preventing unintended sliding of a car seat, as shown in fig. 1, comprising: the system comprises a main controller chip 1, a motor relay 2, a power supply control circuit 3 and a motor diagnosis circuit 4, wherein the power supply control circuit 3 and the motor diagnosis circuit 4 are respectively electrically connected with the main controller chip 1 and the motor relay 2; wherein the content of the first and second substances,
the motor relay 2 is used for controlling the forward rotation or the reverse rotation of the direct current motor to drive the seat connecting rod mechanism to adjust the position of the seat;
the power supply control circuit 3 is used for supplying power to the motor relay 2;
the main controller chip 1 is used for driving the power control circuit 3 after receiving the level input signal; the motor diagnosis circuit is also used for judging whether the diagnosis signal is consistent with the expected signal or not after receiving the diagnosis signal fed back by the motor diagnosis circuit 4, and if not, the power supply control circuit 3 is closed;
and the motor diagnosis circuit 4 is used for feeding back a diagnosis signal of the direct current motor to the main controller chip 1 in real time.
It should be noted that the unintended sliding of the vehicle seat refers to the case where the seat is abnormally slid forward or backward without the driver pressing the forward or backward slide button. In the present invention, when the diagnostic signal does not correspond to the expected signal, the unexpected sliding of the car seat occurs.
In the control device for preventing the unexpected sliding of the automobile seat provided by the embodiment of the invention, the unexpected sliding of the automobile seat can be effectively prevented from influencing the safe driving of a driver through the combined design and interaction of the main controller chip, the motor relay, the power supply control circuit and the motor diagnosis circuit, and the driving safety and reliability are improved.
Specifically, as shown in fig. 2, a level of control of a motor power supply (i.e., a power supply control circuit) and a motor state feedback unit (i.e., a diagnostic circuit) are added to the conventional seat controller, and when a diagnostic signal of the dc motor does not match an expected signal, the main controller chip cuts off the motor power supply in addition to the control circuit which cuts off the dc motor, so as to ensure that the motor can be immediately detected and stop abnormal operation once abnormal operation occurs.
Further, in the control device for preventing unintended sliding of a seat of an automobile according to an embodiment of the present invention, the main controller chip 1 is specifically configured to receive a level input signal from the slide switch after the driver presses the seat forward or backward slide switch, and to drive the power control circuit after receiving the level input signal.
In practical implementation, in the control device for preventing the unexpected sliding of the car seat provided by the embodiment of the invention, the motor diagnosis circuit 4 is specifically used for detecting the voltage value and the current value of the direct current motor in real time and feeding the voltage value and the current value back to the main controller chip. That is, the diagnosis signal of the dc motor includes a voltage value and a current value of the dc motor.
Further, in the control device for preventing the unexpected sliding of the car seat according to the embodiment of the present invention, the main controller chip 1 is further configured to compare the voltage value fed back by the motor diagnosis circuit with an expected voltage value corresponding to the state of the slide switch, and turn off the power control circuit if the voltage value does not match the expected voltage value. The main controller chip 1 is specifically configured to compare a current value fed back by the motor diagnosis circuit with an expected current value corresponding to the state of the slide switch, and to turn off the power supply control circuit if the current value does not match the expected current value.
Specifically, as shown in fig. 3, when the driver presses the seat forward or backward sliding switch, the main controller single chip (i.e., the main controller chip) receives the high-level or low-level input signal provided by the switch, and after receiving the input signal, the single chip drives the power control relay of the power control circuit to power the motor relay, and then drives the motor relay to power the dc motor, so that the dc motor can rotate forward or backward. The forward rotation or the reverse rotation of the direct current motor drives the seat connecting rod mechanism, and the seat can slide forwards or backwards through the connecting rod mechanism. To prevent unintended seat slippage, the present invention adds diagnostic circuitry, including voltage diagnostic and current diagnostic circuitry. Because the voltage value and the current value are different when the direct current motor rotates forwards, reversely or stops, the main controller singlechip can detect the voltage value and the current value fed back in real time and compare the values with the normal expected voltage value and the expected current value corresponding to the state of the switch, thereby identifying whether the direct current motor has unexpected action. Once unexpected action is found, the singlechip of the main controller immediately cuts off the power supply of the motor and simultaneously turns off the drive of the motor relay, so that the direct current motor is ensured to stop running immediately, and the unexpected sliding of the seat is prevented.
Based on the same inventive concept, embodiments of the present invention further provide a control method of a control device for preventing an unexpected sliding of a car seat, and since the principle of solving the problem of the control method is similar to that of the control device for preventing an unexpected sliding of a car seat, the implementation of the control method can be referred to the implementation of the control device for preventing an unexpected sliding of a car seat, and repeated details are omitted.
In practical implementation, the control method of the control device for preventing the unexpected sliding of the car seat provided by the embodiment of the invention, as shown in fig. 4, specifically includes the following steps:

s402, supplying power to the motor relay by the power supply control circuit;
s403, controlling the direct current motor to rotate forwards or backwards by the motor relay to drive the seat connecting rod mechanism to adjust the position of the seat;
s404, simultaneously, feeding back a diagnosis signal of the direct current motor to the main controller chip in real time by the motor diagnosis circuit;
and S405, after receiving the diagnosis signal, the main controller chip judges whether the diagnosis signal is consistent with the expected signal, and if not, the power control circuit is closed.
In the control method provided by the embodiment of the invention, the power supply control circuit can be turned off by executing the steps when the unexpected sliding phenomenon of the automobile seat occurs, so that the operation of the direct current motor is switched, the influence on the safe driving of a driver caused by the unexpected sliding of the automobile seat is effectively prevented, and the driving safety and reliability are improved.

It can be understood that, in addition to steps S401 to S403, the driver normally presses the seat forward or backward, the seat can be adjusted normally, step S404 is to detect the action of the dc motor, and step S405 is to detect that once the dc motor has abnormal action, if the driver does not toggle the switch button but the system fails, the seat slides forward or backward unexpectedly, the power control circuit can be turned off, and the abnormal action of the dc motor is stopped, so as to ensure the safety of driving.
In a specific implementation, in the control method provided in the embodiment of the present invention, the step S404 of feeding back a diagnosis signal of the dc motor to the main controller chip in real time by the motor diagnosis circuit may specifically include: the motor diagnosis circuit detects the voltage value and the current value of the direct current motor in real time and feeds the voltage value and the current value back to the main controller chip.
In a specific implementation, in the control method provided in the embodiment of the present invention, the step S405 includes the step of the main controller chip determining whether the diagnosis signal matches the expected signal, and if not, turning off the power control circuit, which may specifically include: and the main controller chip compares the voltage value fed back by the motor diagnosis circuit with an expected voltage value corresponding to the state of the sliding switch, and closes the power supply control circuit if the voltage value does not accord with the expected voltage value.
