초록 ▼

A hybrid vehicle comprises an internal combustion engine, a traction motor, a starter motor, and a battery bank, all controlled by a microprocessor in accordance with the vehicle's instantaneous torque demands so that the engine is run only under conditions of high efficiency, typically only when the load is at least equal to 30% of the engine's maximum torque output. In some embodiments, a turbocharger may be provided, activated only when the load exceeds the engine's maximum torque output for an extended period; a two-speed transmission may further be provided, to further broaden the vehicle's load range. A hybrid brake system provides regenerative braking, with mechanical braking available in the event the battery bank is fully charged, in emergencies, or at rest; a control mechanism is provided to control the brake system to provide linear brake feel under varying circumstances.

대표청구항 ▼

1. A brake system for a vehicle, said brake system providing regenerative and mechanical braking, and comprising: a brake pedal adapted to be depressed by an operator to control braking;a device for controlling resistance of the brake pedal to depression;a sensor for measuring the displacement of the brake pedal when the brake pedal is depressed;a controller operable to monitor a state of charge of a battery of the vehicle; to control the flow of electrical and mechanical power between the battery, at least one electric motor, and one or more wheels of the vehicle; to control application of regenerative braking force to the one or more wheels, responsive to a signal from said sensor indicating depression of said brake pedal by an operator; and to control said device for controlling resistance of the brake pedal to depression;wherein the controller is configured such that the amount of regenerative braking force to be applied to the one or more wheels is proportional to the displacement of the brake pedal, and such that when the operator depresses the brake pedal, indicating that torque is to be applied to the one or more wheels in order to brake the vehicle, and when the battery is not fully charged, the controller (a) causes the at least one electric motor to accept torque from the one or more wheels to generate electric energy, the energy being stored in the battery, thus effecting regenerative braking; and (b) causes feedback to be provided to the operator, wherein the feedback provided to the operator by the controller responsive to regenerative braking comprises a controlled resistance of the device to depression of the brake pedal by the operator, said resistance varying proportional to the degree of regenerative braking; andwherein the brake system is configured such that:after the brake pedal has been depressed by the operator to at least a predetermined displacement, additional displacement of the brake pedal by the operator directly causes mechanical braking to be effected; andwhen regenerative braking is not available, the resistance to depression of the brake pedal in a portion of its movement up to the predetermined displacement is substantially reduced. 2. The system of claim 1, wherein the brake system is configured such that mechanical braking is effected when the amount of torque to be applied to the one or more wheels responsive to depression of the brake pedal by the operator in order to brake the vehicle exceeds the amount of torque that can be applied by regenerative braking. 3. The system of claim 1, wherein the resistance to depression of the brake pedal is varied by said device by controllably varying the degree of opening of a variable orifice in a cylinder having a piston sliding therein connected to said brake pedal.
