The present invention discloses an electromechanical compound transmission device for a tracked vehicle. The electromechanical compound transmission device includes a front transmission mechanism, a power coupling mechanism, an independent drive mechanism, and convergent planetary gearsets arranged on both sides of the power coupling mechanism. The present invention can not only implement driving, steering, and other functions of a vehicle, but also provide sufficient electric energy for a vehicle-mounted device. In other words, a series mode can be adopted to satisfy a torque output requirement, and is mainly used for low and medium-low speed driving, as well as reverse driving and climbing steep slopes; and a series-parallel mode can also be adopted to satisfy requirements of high and medium-high speed driving, and can achieve relatively high transmission efficiency and fuel economy.

A driveline includes an engine, a transmission configured to couple to an axle of the electrified military vehicle, a tractive motor coupled to the transmission, an engine clutch positioned between the engine and the tractive motor, and an accessory drive. The accessory drive includes an accessory motor, an accessory clutch including a first portion and a second portion, an accessory coupled to the first portion, a first belt coupling the first portion to the accessory motor, and a second belt coupling the second portion to the engine.

A military vehicle includes an engine, an energy storage system, an accessory drive coupled to the engine and including an air compressor and a first motor, a second motor coupled to an axle, and a clutch positioned between the engine and the second motor. The clutch is spring-biased into engagement with the engine and pneumatically disengaged by an air supply selectively provided thereto based on operation of the air compressor. In an engine mode, (i) the clutch does not receive the air supply such that the engine is coupled to the second motor and (ii) the engine drives (a) the accessory drive and (b) the axle through the second motor. In the electric mode, (i) the first motor drives the air compressor to compress air to facilitate supplying the air supply to the clutch to disengage the clutch and decouple the engine from the second motor and (ii) the second motor drives the axle.

A driveline includes a driver configured to be positioned between an engine and a transmission. The driver includes a housing, a motor/generator, and a clutch. The housing includes an engine mount configured to couple to the engine and a backing plate configured to couple to the transmission. The motor/generator is disposed within the housing and configured to couple to an input of the transmission. The clutch is disposed within the housing and coupled to the motor/generator. The clutch is configured to selectively couple an output of the engine to the motor/generator. The clutch is configured to be spring-biased into engagement with the engine and pneumatically disengaged by an air supply selectively provided thereto.

A military vehicle include a driveline. The driveline includes a first driver including an engine, an energy storage system, an accessory drive coupled to the engine, a transmission coupled to at least one of the front axle or the rear axle, and a second driver coupled to the engine and the transmission. The accessory drive includes a plurality of accessories and a first motor. The first motor is electrically coupled to the energy storage system. The first motor is positioned to facilitate selectively driving the plurality of accessories. The second driver includes a second motor electrically coupled to the energy storage system.

A military vehicle includes a chassis, a front end accessory drive (FEAD), and circuitry. The chassis includes an engine and an integrated motor generator (IMG). The FEAD includes multiple accessories and an electric motor-generator. The circuitry is configured to operate the military vehicle according to different modes. The circuitry is configured to receive a user input indicating a selected mode of the modes, and operate the chassis and the FEAD of the military vehicle according to the selected mode. The modes include an engine mode and an electric mode. In the engine mode, the engine drives the FEAD and the tractive elements of the military vehicle through the IMG for transportation. In the electric mode, the engine is shut off to reduce a sound output of the military vehicle and the IMG drives the tractive elements of the military vehicle for transportation and the electric motor-generator drives the FEAD.

A front end accessory drive (FEAD) for a military vehicle. The FEAD includes a first belt, a second belt, multiple accessories, an electric motor-generator, at least one other accessory, and a sprag clutch. The accessories and the electric motor-generator are coupled with the first belt. The at least one other accessory, the first belt, and the second belt are coupled with the sprag clutch. The second belt is configured to couple with an output shaft of an engine of the military vehicle and be driven by the output shaft of the engine to drive the sprag clutch. The sprag clutch is thereby configured to drive the at least one other accessory and the first belt, and the first belt is thereby configured to drive the plurality of accessories, and the electric motor-generator.

Techniques pertaining to an autonomous police vehicle are described. A method may involve a processor associated with an autonomous vehicle obtaining an indication of violation of one or more traffic laws by a first vehicle. The method may also involve the processor maneuvering the autonomous vehicle to pursue the first vehicle. The method may further involve the processor remotely executing one or more actions with respect to the first vehicle.

A military vehicle includes an engine configured to drive a front-end accessory drive and a tractive element, an energy storage system including a battery and a controller configured to control the flow of electricity to and from the energy storage system, a first motor/generator, and a second motor/generator. The first motor/generator is electrically coupled to the energy storage system and configured to selectively draw power from the energy storage system to drive the front-end accessory drive and be driven by the front-end accessory drive to generate electricity and supply electricity to the energy storage system to charge the battery. The integrated motor/generator is electrically coupled to the energy storage system and configured to selectively draw power from the energy storage system to drive the tractive element and be driven by the engine to generate electricity and supply electricity to the energy storage system to charge the battery.

A military vehicle includes a frame, axle assemblies coupled with the frame that are configured to be driven to transport the military vehicle, an internal combustion engine configured to drive the axle assemblies, an electric motor configured to drive the axle assemblies, and processing circuitry.
