An ECU switches a control mode to an HV mode when an SOC decreases to a lower limit during an EV mode. The ECU calculates an evaluation value D of high-rate deterioration indicating a deterioration component of a secondary battery due to non-uniformity in salt concentration in a battery. The ECU executes high-rate deterioration inhibiting control when the HV mode is currently selected and when the battery is evaluated as deteriorating based on the evaluation value D, the high-rate deterioration inhibiting control being control for increasing the SOC by making a control target of the SOC higher than the lower limit of the SOC. On the other hand, the ECU does not execute the high-rate deterioration inhibiting control when the EV mode is currently selected.

In one or more embodiments of the present invention, one or more processors receive a fuel sensor reading from a fuel sensor on a vehicle. The processor(s) receive an environmental state of a route being taken by the vehicle to a destination and a biometric sensor reading that describes a biometric state of a driver of the vehicle. The processor(s) determine whether the remaining fuel will be sufficient for the vehicle to reach the destination subject to the constraints of the environmental state of the route being taken by the vehicle and the biometric state of the driver of the vehicle, and then modify an appearance of a fuel gauge on the vehicle based on whether the remaining fuel will be sufficient for the vehicle to reach the destination.

A method determines a force to be transmitted to driving wheels of a vehicle provided with a hybrid power train with several gear ratios and a traction battery. The method includes determining, over all of a speed range that the vehicle is capable of achieving, a maximum force that the power train is theoretically capable of transmitting to the wheels in predetermined nominal conditions of charge of the traction battery and/or of outside temperature and/or of atmospheric pressure; and determining, over all of the speed range, a drivability force that the power train is capable of transmitting to the wheels. The drivability force confirms that whatever the value of the speed of the vehicle, the drivability force is less than or equal to the maximum force; and the drivability force evolves within the speed range without exhibiting an inflexion point at values of the speed requiring a gear change.
