Embodiment Construction

[0038] Preferred embodiments of the two-wheeled vehicle according to the present invention will be described in detail below with reference to the drawings.

[0039] [Structure of this embodiment]

[0040] figure 1 This is a schematic block diagram of a motorcycle 10 according to the present embodiment, and the motorcycle 10 is applied to, for example, an electric bicycle. The structure of an electric bicycle is known (for example, refer to Japanese Patent Application Laid-Open No. 6-156360), and therefore, a detailed description of the structure will be omitted.

[0041] The two-wheeled vehicle 10 includes an accelerator state sensor (APS) 12 , a vehicle speed sensor (wheel speed sensor) 14 , a PDU 16 , and a motor (electric motor) 18 .

[0042] The APS 12 successively detects the amount of accelerator opening that is the amount of operation of the accelerator grip 20 by the driver, and outputs an analog signal indicating the detection result to the PDU 16 . The vehicle sp...

Abstract

The invention relates to a two-wheel vehicle. According to the invention, torque generated by human labor and torque generated by an electric motor are transmitted to wheels like an electric bicycle and skidding is detected at a low cost. In the two-wheel vehicle (10), a vehicle speed sensor (14) detects rear wheel rotation speed (Vrr). The skid detection unit (36) detects skid of the two-wheel vehicle (10) in a condition that the rear wheel rotation speed (Vrr) increases with the lapse of time and the load rate (Dt) of control signals supplied to a motor drive circuit (32) does not change and when the rear wheel rotation speed (Vrr) is increased to a rotation speed threshold value (Vbs).

Description

technical field [0001] The present invention relates to a two-wheeled vehicle that transmits torque generated by human power and torque generated by an electric motor to wheels. Background technique [0002] In Patent Document 1, it is disclosed that the slippage of the motorcycle is detected from the speed difference between the rotation speed of the front wheel and the rotation speed of the rear wheel, the occurrence of the slip is reported to the driver, and at the same time, an engine operation corresponding to the occurrence of the slip is performed. output control. [0003] [Patent Document 1] Japanese Patent Laid-Open No. 2012-206550 [0004] Applying the skid detection technology of Patent Document 1 to electric bicycles detects the rotation speed of the front wheel and the rotation speed of the rear wheel. Therefore, a plurality of speed sensors is required, and there is a problem of high cost. Contents of the invention [0005] Therefore, an object of the prese...
