A conversion device is provided for an automobile, including a conversion circuit, input port(s), output port(s), and a power flow sensor. The input port function to receive a power input. The conversion circuit includes a DC bus and a plurality of converters. An input side of the DC bus is connected to an input conversion module, and an output side of the DC bus is connected to a DC / DC converter, a DC / AC inversion converter, and a bi-directional DC / DC converter for converting the power input from the input port. The power flow sensor is connected between the input port and the input conversion module of the input side to sense and feed power flow of the power input from the input port to the conversion circuit for carrying out power conversion. The output port is connected to the converters of the output side for output of power. As such, the power input at the input port is converted by the conversion circuit and supplied through the output port and the power flow sensor detects the power flow of the input power at the input port to various power sources to continuously supply power to the automobile thereby providing practicability and convenience of ensuring continuous supply of power and substantially enhancing the cruising distance of the automobile.

Provided is an air conditioning system that conditions the air inside the passenger compartment of an automobile mounted with a secondary battery or fuel cell that drives the wheels via a motor. Said air conditioning system comprises a catalytic heater, an air-conditioning duct, and an air-conditioning fan. The catalytic heater produces heat by supplying an oxidizing gas and a fuel to a catalyst. The air-conditioning duct is connected to an air intake and a vent, the air-conditioning fan is provided inside the air-conditioning duct, and air is circulated inside the passenger compartment. The provided air conditioning system uses the heat produced by the catalytic heater to condition the air inside the air-conditioning duct, thereby conditioning the air inside the passenger compartment. In automobiles mounted with a secondary battery or fuel cell that drives the wheels via a motor, such as electric automobiles, hybrid vehicles, and fuel cell automobiles, the provided air-conditioning system reduces the use of the power from the secondary battery or the like for heating, thereby preventing the driving range or life from decreasing and allowing efficient conditioning of air.

A vehicle control system is provided. The vehicle control system is applied to a vehicle having a clutch device to selectively connect and disconnect a power transmission route between a prime mover and drive wheels, and configured to disconnect the power transmission route during running to allow the vehicle to coast. The vehicle control system is comprised of: a vehicle speed detection means; an execution means that executes a coasting control when an operating amount of an accelerator is reduced to be smaller than a predetermined value during running, by bringing the clutch device into disengagement to disconnect the power transmission route so as to allow the vehicle to coast; an updating means that updates a lowest speed of the vehicle during execution of the coasting control; and a termination means that terminates the coasting control by bringing the clutch device into engagement to connect the power transmission route, when a difference between a current vehicle speed and the latest lowest vehicle speed exceeds a predetermined value.

An automatic transmission for an electric vehicle is provided with a belt type continuously variable transmission mechanism (3) in which an input unit (30P) is arranged so as to be capable of rotation relative to an input shaft (2A) and that adjusts a pulley winding radius and a clamping force by an electric actuator (80A) and a mechanical reaction force mechanism (80B, 9), a constant mesh parallel shaft geared transmission mechanism (4) that is coupled to an output unit (30S) of the belt type continuously variable transmission mechanism (3) and has a plurality of speed stages, an input gear (21) that is arranged on the input shaft (2A) so as to be capable of relative rotation and is drivably coupled to one of a plurality of transmission gears fixedly installed on an output-side shaft of the constant mesh parallel shaft geared transmission mechanism (4), and a meshing clutch mechanism (5A) that is arranged on the input shaft (2A) and selectively couples either one of the input unit (30P) of the belt type continuously variable transmission mechanism (3) or the input gear (21) to a main electric motor (1).

A vehicle control system is provided. The vehicle control system is applied to a vehicle comprising an engine having cylinders, a power transmission route between the engine and drive wheels, and a clutch selectively connecting and disconnecting the power transmission route. The vehicle control system disconnects the power transmission route during running to allow the vehicle to coast. The vehicle control system is comprised of: a means that detects a vehicle speed; a means that detects an operation of an accelerator by a driver; a means that detects a speed of the engine; an execution means that executes a coasting control when an operating amount of an accelerator is reduced to be smaller than a predetermined value during running, by bringing the clutch device into disengagement to disconnect the power transmission route; and an engine control means that reduces number of combusting cylinders during the coasting control while reducing the engine speed to an idling speed that is lower than that of a case in which the coasting control is not carried out.

A power supply system includes a first drive motor, a second drive motor, a first power line to which a first inverter and a first battery are connected, a second power line to which a second inverter and a second battery are connected, a voltage converter that converts a voltage between the first power line and the second power line, and an ECU that operates the first and second inverters and the voltage converter and controls charging and discharging of the first and second batteries. In a case where total required power is larger than first outputtable power of the first battery, the ECU discharges a shortage of power from the second battery to the second power line, wherein the shortage of power is obtained by excluding an amount that is output by the first battery from the total required power.
