Title:
VEHICLE CONTROL DEVICE AND VEHICLE CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/006261
Kind Code:
A1
Abstract:
The purpose of the present invention is to realize a control device having operation continuity during failure at a lower level of redundancy to reduce cost. In order to achieve the purpose, the following measures are taken in the present invention. (1) Different motive power (energy) sources included in a hybrid driving system are regarded as redundant motive power (energy) sources. (2) A control unit (first control unit) of a transmission part for mixing motive powers (energy) from the different motive power (energy) sources so as to transmit energy to a driving wheel is provided with a function of operation continuation during failure. (3) Control units (second control unit, third control unit) for controlling the different motive power (energy) sources are provided with common failure countermeasures and are configured not to lose the control functions in case of the same failure. (4) An energy management control unit (fourth control unit) for controlling the mixture ratio of the motive powers (energy) from the different motive power (energy) sources in the transmission part performs control such that, during failure of one of the motive power (energy) sources or the control unit of the motive power (energy) source, the transmission part transmits energy to the driving wheel by a motive power (energy) from the other motive power (energy) source.
