Problems solved by technology

That is, although individual units can be inspected by using a dedicated detector, each unit cannot be inspected in the state of the vehicle as a final product form
Therefore, in the case where a failure is detected in the state of the vehicle (for example, a failure occurs at the time of a general test immediately before shipment or at the time of use), it cannot be specified whether the area of ​​the failure is located in the drive unit itself or in a part combined with other units, As a result, the entire hybrid system had to be replaced

Abstract

The present invention discloses a hybrid vehicle (100) in which, first, an engine (5) is locked by an engine shaft locking mechanism (13). A first motor (MG1) is operated by torque control and a second motor (MG2) is operated by number-of-revolutions control. Torque for controlling the second motor (MG2) in this state is obtained. Based on the obtained control torque, whether the first motor (MG1) is normal is checked. Successively, the second motor (MG2) is operated by the torque control and the first motor (MG1) is operated by the number-of-revolutions control to check whether the second motor (MG2) is normal in a similar manner.

Description

technical field [0001] The present invention relates to a hybrid vehicle detection system and method for detecting performance of a hybrid vehicle. More particularly, the present invention relates to a hybrid vehicle detection system and method capable of detecting the performance of a drive unit including a drive source (motor) for a hybrid vehicle and specifying the cause of the poor performance for a vehicle with poor performance. Background technique [0002] In recent years, a hybrid vehicle that uses an engine and an electric motor as a power source and travels while controlling the engine and electric motor has attracted attention from the viewpoint of low pollution and the like. In such a hybrid vehicle, a power transmission unit (transaxle) for outputting power obtained from an electric motor and an engine to a drive shaft via a transmission is installed. For example, this technique is disclosed in JP2001-164960A. [0003] Hybrid vehicles are required to have high...
