    Vehicle control method and control device {Method and apparatus for controlling driving car}
    The present invention relates to a driving control method and a control apparatus of a vehicle for safe driving by controlling the engine output of the vehicle, the gear stage of the gear transmission and the braking force of the braking device according to the inclination of the road on which the vehicle travels.
    In general, there are various roads, including flat roads, uphill roads, and downhill roads.
    When driving these various roads, it is necessary to appropriately adjust the speed of the gear transmission of the vehicle, the braking device and the engine output according to the inclination of the road.
    In particular, when driving on a steep slope, the driver of the vehicle must adjust the driving speed of the vehicle by repeatedly using the gear transmission and the brake system.
    When driving downhill roads that are severely inclined, the brakes are overheated when the driving speed of the vehicle is adjusted by operating only the brake pedal of the brake system, without using the engine brake and the brake pedal of the brake system properly. When the brake pedal is stepped on, the braking device does not operate, and accidents often occur.
    The occurrence of such an accident is a problem for the inexperienced drivers who are inexperienced in driving a vehicle, or the elderly who have low reflexes, and thus have a higher risk of accidents.
    Accordingly, an object of the present invention is to detect the inclination of the road on which the vehicle is currently traveling, and to adjust the output of the engine, the gear stage of the gear transmission, and the braking force of the braking device according to the detected inclination of the road to enable safe driving. To provide a driving control method and a control device.
    According to a traveling control method and control apparatus of a vehicle of the present invention for achieving this object, by using a horizontal detection means such as a horizontal gyroscope (gyroscope) to generate a signal according to the slope of the road currently driving the vehicle, The output signal of the horizontal detection means is compared with a reference value preset in the comparator.
    The controller determines the inclination of the driving road as a result of comparing the output signal of the horizontal detection means with a preset reference value, and controls the engine output, the gear transmission, and the braking device according to the determination result.

    2 is a signal flow diagram illustrating a driving control method of the present invention.

    Hereinafter, a driving control method and a control apparatus of a vehicle of the present invention will be described in detail with reference to the accompanying drawings.
    1 is a circuit diagram showing the configuration of a traveling control device of the present invention.
    Here, reference numeral 10 denotes a horizontal gyroscope which is a horizontal detection means installed in the vehicle and generating a signal according to the inclination of the road on which the vehicle travels.
    Reference numeral 12 is a comparator for comparing the inclination signal of the road output by the horizontal gyroscope 10 with a preset reference value and outputting a comparison result signal.
    Reference numeral 14 denotes a comparison result signal output by the comparator 12 to determine the inclination of the road on which the vehicle travels, and according to the determined inclination, the output of the engine 16, the gear stage of the gear transmission 18, and the braking device 20. Control unit such as a microcomputer to control the braking force.
    In the traveling control apparatus of the present invention configured as described above, when the vehicle travels, the horizontal gyroscope 10 detects the inclination of the road on which the vehicle currently runs, outputs a signal according to the inclination, and the horizontal gyroscope 10 outputs the The signal of one inclination is input to the comparator 12 and compared with a predetermined reference value and output.
    As such, the comparison signal output from the comparator 12 is input to the control unit 14. The control unit 14 determines the inclination of the road on which the vehicle currently runs as a comparison signal input, and determines the inclination of the engine according to the determined inclination of the road. The output of 16 is controlled, the gear stage 18 is adjusted, and the braking force of the braking device 20 is controlled.
    For example, the controller 14 divides the road on which the vehicle travels into a normal road, a weak uphill road, a weak downhill road, a normal uphill road, a normal downhill road, a steep uphill road, and a steep downhill road, as shown in Table 1 below. The driving signal of the comparator 12 determines the slope of the road and controls the driving of the vehicle.
    SlopeControl Status A normal roadDoes not correspond Weak uphill roadWarning (Caution) Weak downhill road Normal uphill roadSlight increase in engine power Downhill roadBraking is weak after warning, gear shift adjustment, engine power slightly reduced Steep uphill roadIncreased output of the engine Steep downhill roadStrong brake, warning gear shifting
    2 is a signal flowchart illustrating a driving control method of the present invention.
    As shown therein, the control unit 12 inputs a comparison signal output by the comparator 12 in step S20, and determines the inclination of the road on which the vehicle currently travels in steps S21 to S27 using the input comparison signal. do.
    As a result of determining the inclination of the road, in the case of the normal road in step S21, the control unit 14 does not respond in step S28, and when it is determined in step S22 that the road is a weak uphill road, the control unit 14 performs the step At S29, a warning sound is output through an alarm unit (not shown) to draw attention of the driver, and when it is determined at step S23 that the road is a normal uphill road, the output of the engine 16 is determined at step S30. Slightly increasing, when it is determined that the steep slope uphill road in step S24, the output of the engine 16 is increased a lot in step S31 so that the vehicle can easily drive the steep uphill road.
    If it is determined in step S25 that the road is weak downhill, the controller 14 outputs a warning sound in step S33 to draw attention to the driver, and in step S26, if it is determined that the road is normal downhill road S33. If the braking device 20 is weakly operated, the gear shift stage 18 is adjusted so that the engine brake is slightly operated, the output of the engine 16 is slightly reduced, and if it is determined that the steep downhill road is in step S27. In step S31, the braking device 20 is strongly operated, the gear shift stage 18 is adjusted to make the engine brake operate a lot, and the output of the engine 16 is greatly reduced.
    As described above, according to the present invention, when the vehicle travels on the inclined road, the uphill road can be easily driven by controlling the output of the engine, the gear transmission, and the brake according to the inclination of the inclined road, and the brake on the downhill road. Excessive pedaling can be prevented, as well as reducing accidents.
