Abstract: A program delivery center is a program update device which updates a program of an ECU mounted in a vehicle, wherein a right holder specification unit specifies a right holder who has a right to execute the update of the program on the basis of information regarding the vehicle, and a reprogramming guide execution unit sets and outputs program update guide notification to the right holder. Accordingly, the update of the program by a person other than the right holder can be avoided, thereby improving security. Furthermore, since the update of the program is notified to the right holder which can execute the update of the program, a program update execution frequency increases compared to a case where a user who cannot execute the update of the program is notified, thereby prompting the execution of the program update.

Abstract: A hybrid vehicle includes a regenerative charging area detection section, a recovery loss estimation section, and a motor use ratio increase section. The regenerative charging area detection section detects arrival of a regenerative charging possible area in which a regenerative charging from a motor to a battery is possible. The recovery loss estimation section estimates a recovery loss of the regenerative charging based on a regenerative charge amount in the regenerative charging possible area and a current remaining battery amount in response to detection by the regenerative charging area detection section. In response to estimation by the recovery loss estimation section, before the arrival at the regenerative charging possible area, the motor use ratio increase section increases a use ratio of the motor so as to decrease a remaining battery amount while limiting the temperature of the battery to a predetermined temperature range.

Abstract: An electrically heated catalytic converter (EHC) and a battery are connected to an alternator via a changeover switch. The changeover switch connects either of the EHC and the battery to the alternator. The slip-detecting device detects the rotational speed of the alternator from the frequency of the ripple in the output voltage of the alternator when the EHC is connected to the alternator, i.e., when the battery is isolated from the alternator. When the battery is isolated from the alternator, the output voltage of the alternator is raised, and the amplitude of the ripple becomes large accordingly. Further, since the battery is isolated, the ripples in the output voltage are not smoothed by the battery. Therefore, the rotational speed of the alternator is accurately detected. The slip-detecting device detects the slip of the driving belt of the generator based on the rotational speeds of the driver and the alternator.

Abstract: A battery and an electrically heated catalytic converter (EHC) are connected to an alternator in a parallel arrangement via a changeover switch. The changeover switch operates between a first position where it connects the battery to the alternator and a second position where it connects the EHC to the alternator. An electronic control unit (ECU) is provided for controlling the changeover switch and the alternator. When the changeover switch is to be switched between the first and the second position, the ECU first terminates the power generation of the alternator before it actually switches the changeover switch in order to reduce the electric current flowing through the switch.
