  • Patent number: 11312360
    Abstract: If the destination has not been input, it is judged whether the present location is on the expressway (step S32). If the judgement result of the step S32 is positive, it is judged whether or not the actual SOC is less than or equal to the threshold TH2 (step S34). If the judgement result of the step S34 is positive, the restoring control is executed (step S36). Subsequent to the step S34 or S36, it is judged whether or not the vehicle is still on the expressway (step S38). If the judgement result of the step S38 is positive, it is judged whether or not the actual SOC is greater than or equal to the SOC_T2 (step S42). If the judgement result of the step S42 is positive, the maintaining control is executed (step S44).
