Electric Motorcycle

Abstract

An electric motorcycle comprises a hydraulic pump, an oil passage, a first hydraulic pressure detecting section for detecting a hydraulic pressure in the oil passage, a hydraulic pressure determiner section for determining if the hydraulic pressure is less than a first allowable value, a pump state determiner section for determining if an activation command is output to the hydraulic pump, and a warning output section for outputting a warning signal according to a result of the determination performed by the hydraulic pressure determiner section and a result of the determination performed by the pump state determiner section, wherein the warning signal is not output when the activation command is not output and the hydraulic pressure is less than the first allowable value; and the warning signal is output when the activation command is output and the hydraulic pressure is less than the first allowable value.

1 . An electric motorcycle comprising:
 a hydraulic pump;   an oil passage through which oil forcibly fed by the hydraulic pump flows;   a hydraulic pressure detecting device for detecting a hydraulic pressure in the oil passage;   a hydraulic pressure determiner unit for determining whether or not a value of the hydraulic pressure detected by the hydraulic pressure detecting device is less than a first allowable value;   a pump state determiner unit for determining whether or not an activation command is output to the hydraulic pump; and   a warning output device for outputting a warning signal according to a result of the determination performed by the hydraulic pressure determiner unit and a result of the determination performed by the pump state determiner unit;   wherein the warning output device does not output the warning signal when the pump state determiner unit determines that the activation command is not output to the hydraulic pump and the hydraulic pressure determiner unit determines that the value of the hydraulic pressure in the oil passage is less than the first allowable value; and   wherein the warning output device outputs the warning signal when the pump state determiner unit determines that the activation command is output to the hydraulic pump and the hydraulic pressure determiner unit determines that the value of the hydraulic pressure in the oil passage is less than the first allowable value.   
     
     
         2 . The electric motorcycle according to  claim 1 , comprising:
 a pump control unit for controlling activation of the hydraulic pump;   wherein the pump control unit activates the hydraulic pump before driving; and   wherein the hydraulic pressure determiner unit determines whether or not the value of the hydraulic pressure in the oil passage is less than the first allowable value, after the hydraulic pump is activated.   
     
     
         3 . The electric motorcycle according to  claim 1 ,
 wherein the hydraulic pressure detecting device is a hydraulic sensor; and   wherein the hydraulic pressure determiner unit determines whether or not the value of the hydraulic pressure in the oil passage is less than the first allowable value, based on a value of the hydraulic pressure detected by the hydraulic pressure detecting device.   
     
     
         4 . The electric motorcycle according to  claim 1 ,
 wherein the oil passage connected to an outlet of the hydraulic pump is provided with a filter, and a hydraulic oil inlet of a driving motor or a hydraulic oil inlet of a transmission in this order from an upstream side; and   wherein the hydraulic pressure detecting device is provided at either one of or both of a first mounting position which is between the outlet of the hydraulic pump and the filter and a second mounting position which is between the filter and the hydraulic oil inlet.   
     
     
         5 . The electric motorcycle according to  claim 1 , comprising:
 a second hydraulic pressure determiner unit for determining whether or not the value of the hydraulic pressure in the oil passage is less than a second allowable value; and   a torque control unit for suppressing torque of a driving motor when the second hydraulic pressure determiner unit determines that the value of the hydraulic pressure in the oil passage is less than the second allowable value.   
     
     
         6 . The electric motorcycle according to  claim 5 ,
 wherein the hydraulic pressure detecting device is a hydraulic sensor; and   wherein the torque control unit decides a degree to which the torque is suppressed based on the value of the hydraulic pressure detected by the hydraulic pressure detecting device.   
     
     
         7 . The electric motorcycle according to  claim 5 ,
 wherein the oil passage is a passage used to lubricate or cool a driving system; and   wherein the torque control unit inhibits the torque from being suppressed, before a predetermined time passes after the hydraulic pump starts to operate.
