A vehicle that includes: a towing axle connected to a heat engine; a directional axle; and a complementary axle that is neither directional nor motor-driven. When the vehicle is hybridized according to the method of the invention, the wheels of the complementary axle are removed and replaced by in-wheel motors, each connected with an inverter specifically dedicated for supplying electrical power thereto from an electrical power battery. A control housing is also provided, that has built-in acceleration control devices connected to the accelerator pedal, and built-in deceleration control devices connected to the brake pedal, so as to control and monitor all the mechanisms needed for the driver to transparently accelerate and decelerate the vehicle.

A system according to the principles of the present disclosure includes a cruise control module, an engine control module, and a brake control module. The cruise control module determines a cruise torque request based on at least one of a following distance of a vehicle and a rate at which the vehicle is approaching an object. The engine control module determines a negative torque capacity of a powertrain. The powertrain includes an engine and an electric motor. The brake control module applies a friction brake when the cruise torque request is less than the negative torque capacity of the powertrain.

A control device of a vehicle includes a discharge control unit. The discharge control unit, in a case where a plurality of regenerative sections are included in a scheduled traveling route, extracts a first regenerative section on a vehicle side, a second regenerative section closest to the first regenerative section, and a dischargeable section between the first regenerative section and the second regenerative section. The discharge control unit, in a case where a predicted regenerative electric power amount in the first regenerative section is greater than a predicted discharge electric power amount in the dischargeable section, sets a section obtained by merging the first regenerative section, the second regenerative section, and the dischargeable section as a control target section, and performs the discharge control based on a remaining capacity of a power storage device and a predicted regenerative electric power amount in the control target section.

A control device of a vehicle includes a discharge control unit configured to, in a case where a regenerative section is included in a scheduled traveling route of the vehicle, perform a discharge control for increasing a discharge amount of a power storage device as compared with a case where the regenerative section is not included in the scheduled traveling route. The discharge control unit is configured to determine a target discharge electric power amount, which is a target value to be discharged before the vehicle reaches a start point of the regenerative section, based on a predicted regenerative electric power amount that is capable of being generated in the regenerative section, and perform the discharge control based on the target discharge electric power amount and a parameter that changes in accordance with a distance from the vehicle to the start point.

A method may include distributing target torque to target engine torque of an engine and target motor torque of a motor according to a predetermined control logic according to driver demand torque, comparing torques which determines whether actual torques of the engine and the motor are smaller than the target engine torque and the target motor torque, comparing whether a time period during which a state where a state where the torque of the engine or the motor is insufficient is maintained is a predetermined reference time or more, determining that any one of the engine and the motor is failed, when the time during which a state where the state where the torque of the engine or the motor is insufficient is maintained is the reference time or more, and controlling limp-home which limits the target engine torque of the engine, the target motor torque of the motor, and the regenerative braking amount of the motor.
