Abstract

The object of the present invention is to provide a drive control method for motorcycle, which is capable of preventing overload of a drive system under any usage patterns in order to protect the drive system. Further, in an abruptly starting operation of a vehicle in a condition when the vehicle is standing on a driving surface, the present invention prevents an unexpected quick starting of the vehicle in order to eliminate impact to a drive device caused by excessive driving force. The construction of the present invention comprises: a drive source motor; a controller that controls rotation of the drive source motor; and a speed sensor that detects revolution speed of a front wheel. The controller controls the rotation of the drive source to maintain a number of revolutions to be under the certain limit value by the controller when the revolution of the front wheel detected by the speed detector is under the set value. When a rider opens a throttle and rotates the drive source at high speed beyond the limit value while the motorcycle is stopping and lifted by a stand and the rider makes release of the stand and starts, the drive system is effectively protected without applying the overload on the drive system from the rear wheel side because the number of revolutions is restricted to be under the limit value. A vehicle 1 comprises front and rear wheels 5, 10 mounted to a vehicle body 2; a stand 20 that is up-and-down rotatably mounted to the vehicle body 2 by a pivot and which, when rotated downward, has an end engageable with a driving surface 11; a drive device 25 that is mounted to the vehicle body 2 and drives the movement of the rear wheel 10; and a control device 35 that controls the drive device 25. When the rotation speed VF of the front wheel 5 reaches a value below the first set value V1 (VF < V1), while the rotation speed VR of the rear wheel 10 reaches a value beyond the second set value V2 that is greater than the first set value V1 (VR > V2 > V1), the control device 35 reduces the rotation speed of the rear wheel 10.

Description

555667 玖 发明, description of the invention (the description of the invention should state: the technical field of the invention, the technology, the content, the embodiment and the simple description of the drawings) [Technical Field of the Ming] The present invention relates to a drive control method for a locomotive, which is Drive with an electric motor or the like. The invention also relates to a rapid-start prevention device for a saddle-type vehicle, which stands on the driving surface of the vehicle and is driven by the driving device after idling, and the state of the wheel immediately after moving the handlebar prevents the rider from driving after the driver has not heard the driving device. What is the degree of wheels and turning speed? I. Prior technology] The previous locomotive used the engine as the driving source, but the electric locomotive with the electric motor as the driving source has been launched from the perspective of environmental protection. &gt; The locomotive has: a drive motor; a controller that controls the rotator of the electric motor; and a speed sensor that detects the rotation speed of the front wheels. A locomotive of a saddle type vehicle is generally constituted as follows. That is, the locomotive has: front and rear wheels, which are supported by the vehicle body; a main tripod, which rotates the vehicle body upwards and downwards, and the end of the rotation can be grounded to the line = Guangshu support the downward rotation state; The acceleration operation unit is to input the rear vehicle 2: the operation amount is increased or decreased, and the driving device is output to the moving top 1 Γ moving device, which is supported by the vehicle body driveable person = wheel driver; and control 褒Position, in order to control the connection of the above-mentioned driving and mounting wheels: the grounding end of the main chatter frame of the above = state and the front vertical wheel are grounded, so that the above-mentioned vehicle body can stand on the running surface, that is, the vehicle can be from (2) ~ 〇67 When the car is stopped, the one end is grounded to the front wheel `` and = the main stand is turned '' to make its turning surface, and the car body is standing on the running surface t so that the rear wheel is away from the line and from the above. Car_from a ^ state, when the vehicle is immediately started to run, for example, the following start operation is used. For example, as described above, in the state where the vehicle body is put on the vehicle body and operated on the driving surface, the knight riding transmission ... "" The working part pushes the driving force of the driving device forward slightly, From this state, the knight bean automatically rotates the above main tripod to release the grounding of the main tripod. You will be grounded by the rear wheels. Then the vehicle is driven by the rear wheels, so that the above-mentioned vehicle starts immediately from a self-sustaining state. Then, the knight operates the acceleration operation part and increases or decreases the operation amount. The driving force corresponding to the operation amount is output from the driving device to the rear wheels, so the vehicle can travel on the running surface at the desired running state such as the desired speed. [Problem to be solved by inventing tellurium] However, for locomotives containing the above-mentioned electric locomotive, the knight is in a state of standing on the main stand to stop the vehicle. The throttle valve is opened to rotate the drive source such as the engine and electric motor at high speed, and the main stand is released to start quickly In this case, because there is an excessive load on the drive system from the rear wheel side, the gears of the drive system may be damaged. The present invention has been made in view of the above-mentioned problems, and an object thereof is to provide a driving control method of a locomotive, which is capable of preventing any excessive action on the driving system from protecting the driving system in any use state. When the locomotive is started, especially the main body of the driving device is electric (3) (3) 555667

Since the driving sound of the motor t is small, it is not easy to audibly know to what extent the wheel rotation speed is after receiving the driving force from the motor. Therefore, 'If the above driving device outputs a large driving force to the rear wheels, and the rotational speed of the rear wheel's industrial driving is high speed,' the knight still does not notice and wants to start the car's auxiliary ', and the grounding of the rear wheels is grounded, then The vehicle may start unexpectedly due to the high-speed idling drive of the rear wheels. At this time, an unnecessary excessive impact force may be added to the above-mentioned driving device, which has an adverse effect on the driving device &lt; 焘 * life. The vehicle with the above-mentioned structure was previously as shown in Japanese Patent Laid-Open No. 11_2050592. According to the above-mentioned publication, a sensor is provided to detect the upward rotation of the main tripod (collapsed). There is a sensor in the stand-alone state when the main body of the main tripod is rotated downward. The detection signal 'stops the driving of the above-mentioned driving device and prevents the rear wheels from idling, so that the vehicle can be prevented from unintentionally and quickly starting from a self-sustaining state. k However, the above-mentioned prior art lacks the above-mentioned general launching operation, which is generally incapable of starting the vehicle immediately from its self-sustaining state. The present invention focuses on the above situation. The problem is to ground the wheels of the vehicle to the main stand. On the one hand, the rear wheels are separated from the running surface and the vehicle is standing on the running surface. When the rear wheels are “second owed”, the grounding of the above-mentioned monopod is cancelled. When the above-mentioned rear wheels are grounded, when the starting operation of the vehicle is immediately started, the knight is prevented from knowing to what extent the wheel rotation speed after the driving device is driven. In order to avoid the need for an excessively large impact on 555667, I invented that the driver was described as bribe. [Summary of the Invention] [Means for Solving the Problems] In order to achieve the above-mentioned object, the locomotive of the present invention has a driving source motor; a protector that controls the rotation of the driving source motor; and a speed sensor that detects the front wheel Rotation speed; characterized in that when the speed sensor detects that the rotation speed of the front wheel is below a fixed value, the controller controls the rotation of the driving source ... to ^ the number of rotations of the driving source is below a certain limit value. Therefore, according to the present invention, for example, when the knight is standing upright on the main tripod (that is, the state where the rotation speed of the front wheel is below the set value (= 0) is detected by the speed sensor, the throttle valve is opened so that the driving source is above a certain limit value. Under Gao Chun's rotation, the number of rotations of the drive source is limited when the main tripod is released, so it can prevent the rush of the locomotive and prevent the drive system from being overloaded from the rear wheel side, effectively protecting the drive system. The device for preventing the rapid start of the saddle-type vehicle of the present invention that solves the above-mentioned problems is as follows.
