and according to its operation, the creep prevention mechanism 1

した。 The brake detector 23 shown in FIG. 2 generates a high-level signal when the brake pedal 24 is depressed, and when released, generates a low-level activation signal for a certain period of time from the monostable multivibrator circuit 26. This is input to the AND circuit 21, and thus, when the brake is released, the corresponding
When a low-level operation signal is input from the brake detector 23 to the AND circuit 21 for a certain period of time, the switching element 22 on the output side becomes non-conductive, and the control valve 13 returns to the open position with spring pressure to prevent creep. The operation of the mechanism 11 is released for a certain period of time.

が入力されるように構成されている。 FIG. 3 shows a detailed configuration of the control circuit 15, in which the idling operation detector 17 is connected to the accelerator pedal 1.
Detection switch 17 closed in the idle position of 6
a, and the switch 17 is turned on during idling operation.
The circuit is configured such that the input potential of the inverting buffer 17b decreases due to the closing of the circuit a, and a high-level signal is input to the AND circuit 21, and the brake detector 23 detects that the brake pedal 24 is opened when the brake pedal 24 is released. A switch 23a is provided, and when the brake is released, the reverse buffer 2 is opened by opening the switch 23a.
3b is lowered, and a low level signal is input to the multivibrator circuit 26 via the second inverting buffer 23c on the output side.
When the input signal from 3c switches from high level to low level, this is used as a trigger to output a low level signal for a certain period of time, and when the brake is released, a signal from the brake detector 23 is sent to the AND circuit 21 when the brake is released. A low level signal is input for a certain period of time. The stop detector 20 includes an oscillating circuit 20a that generates an oscillating voltage when the reed switch 19 is opened and closed, and an integrating circuit 20c that is connected to the oscillating circuit 20a through a transistor 20b to generate a voltage according to the vehicle speed. After amplifying this with an operational amplifier 20d, it is compared with the set voltage using a comparator 20e.
When the vehicle speed is less than the set vehicle speed (for example, 10 km/h), it is determined that the vehicle is approximately at a standstill and the reverse buffer 2 is applied.
The configuration is such that a high level signal is input to the AND circuit 21 via 0f.

キをかけておかなくともクリープを防止できる。 Next, to explain its operation, a high level signal is normally output from the multivibrator circuit 26, and when stopped under idling operation, the creep prevention mechanism 11 is activated regardless of whether or not braking is applied. When stopping on a flat road, you can prevent creep without applying the brakes.

に発進できる。 Furthermore, when moving your foot from the brake pedal 24 to the accelerator pedal 16 on an uphill slope to start, when the brake is released, the brake detector 23 performs a timed operation in which the multivibrator circuit 26 outputs a low level signal for a certain period of time. As a result, the operation of the creep prevention mechanism 11 is immediately canceled and the first speed transmission system G1 is established, and by depressing the accelerator pedal 16 during this timed operation, the vehicle can be smoothly started without moving backward.

防止出来る。 As described above, the present invention includes a brake detector that detects the release of the vehicle's brakes and operates,
This operation releases the creep prevention mechanism, and when the brake is released when starting, engine torque is immediately transmitted through the transmission without waiting for the accelerator pedal to be pressed, allowing the vehicle to climb uphill. It is possible to reliably prevent the vehicle from moving backwards when starting.

きる効果を有する。 In this case, if the creep prevention mechanism remains deactivated when the brake is released, the brake must be constantly applied to prevent creep even when stopped on a flat road surface, which is troublesome. The detector is configured to operate for a certain period of time after the brake is released, so
The creep prevention mechanism is activated even when the brakes are not applied, which has the effect of improving the ability to start on a slope and eliminating the trouble of braking while stopped on a flat road surface.
