    Abstract: An object of the present invention is to provide a vehicle management system, an on-vehicle system, and a vehicle management method capable of providing a vehicle of which an odor level in the vehicle fulfills a predetermined criterion, to a user. The vehicle management system acquires a vehicle interior odor data output by an odor sensor arranged in the vehicle, and determines a type of a vehicle interior odor based on the vehicle interior odor data. The vehicle management system acquires an odor level to be associated with the type of the vehicle interior odor, from the vehicle interior odor data, and determines whether the odor level fulfills a predetermined criterion.

  • Patent number: 11052902
    Abstract: 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.
