Embodiment Construction

[0037] Next, a driving torque control method for a vehicle, such as a two-wheeled vehicle, according to an embodiment of the present invention will be described with reference to the drawings.

[0038] figure 1 is a flowchart showing the driving torque control method according to the present embodiment. As shown in the figure, first, the warping amount is detected or calculated (step S1 ). Here, as an example, the "head tilt amount" refers to the pitch angle of the two-wheeled vehicle. "Pitch Angle" sets the state of the front and rear wheels in contact with the ground as "0", and sets the state of tilting the head as a positive value. Therefore, when it is stated in the specification that "the amount of head tilt is large", it means that the pitch angle is large. In addition, since a two-wheeled vehicle is equipped with suspensions on the front and rear wheels, even if the pitch angle is detected or calculated to be a positive value, it does not necessarily occur that the...

Abstract

In order to provide drive torque control with which acceleration defects and the like can be avoided even when a wheelie occurs, this drive torque control method for a vehicle is a method whereby a wheelie amount for the vehicle is detected or calculated, and when a wheelie occurs the drive torque applied to the rear wheels is reduced to less than the drive torque during the normal state, and when the wheelie amount decreases the drive torque is maintained or increased.

Description

technical field [0001] The present invention relates to driving torque control of vehicles, in particular to a driving torque control method, a driving torque control device and a vehicle equipped with these methods and devices capable of controlling cocking during acceleration, wherein cocking refers to the phenomenon of front wheel floating. Background technique [0002] The rear wheels of a vehicle such as a general two-wheeled vehicle (motorcycle) form drive wheels, and the vehicle body is accelerated by the rear wheels. At this time, due to the positional relationship between the point where the rear wheels contact the road surface and the center of gravity of the vehicle body, a predetermined moment is generated with respect to the center of gravity. This moment generated at the time of acceleration is a moment acting in a direction to float the front wheels of the two-wheeled vehicle. Therefore, if a sudden accelerator operation is performed while the two-wheeled veh...
