摘要： Vehicles may be composed of a relatively few number of “modules” that are assembled together during a final assembly process. An example vehicle may include a body module, a first drive module coupled to a first end of the body module, and a second drive module coupled to a second end of the body module. One or both of the drive modules may include a pair of wheels, a battery, an electric drive motor, and/or a heating ventilation and air conditioning (HVAC) system. One or both of the drive modules may also include a crash structure to absorb impacts. If a component of a drive module fails or is damaged, the drive module can be quickly and easily replaced with a new drive module, minimizing vehicle down time.

摘要： A method for operating a transmission of a vehicle, where the transmission couples a drive machine of the vehicle to a driven wheel of the vehicle and has different rotational speed transmission ratios. The method determines that a special load situation prevails or will prevail at the driven wheel of the vehicle. The method determines a shift time or a shift vehicle position, at which a load on the drive machine is less than or equal to a load threshold value. The method adapts the rotational speed transmission ratio of the transmission for the special load situation at the shift time or at the shift vehicle position.

摘要： A propulsion system, control system, and method are provided that use model predictive control to generate an initial selected engine output torque value. A minimum torque limit is determined by selecting a minimum acceptable engine output torque. A maximum torque limit is determined by selecting a maximum acceptable engine output torque. A desired engine output torque value is set as: a) the minimum torque limit, if the initial selected engine output torque value is less than the minimum torque limit; b) the maximum torque limit, if the initial selected engine output torque value is greater than the maximum torque limit; or c) the initial selected engine output torque value, if the initial selected engine output torque value is neither greater than the maximum torque limit nor less than the minimum torque limit.

摘要： A control device for a vehicle includes a failure detector to detect failure in a cooling device to cool an internal combustion engine of the vehicle. An acceleration operation sensor is to detect an acceleration operation amount indicating a target acceleration. Circuitry is configured to control a power output from the internal combustion engine in accordance with the acceleration operation amount, control an air fuel ratio of air-fuel mixture in the internal combustion engine to be in a richer side with respect to a predetermined air fuel ratio if the acceleration operation amount exceeds a high load threshold, limit the power output from the internal combustion engine if the failure detector detects the failure, and prohibit the air fuel ratio from being controlled to be in the richer side even if the acceleration operation amount exceeds the high load threshold if the failure detector detects the failure.

摘要： A method of protecting a multi-function drive axle system from damage, comprising the steps of: determining the axle torque and speed from sensors positioned on the multi-function drive axle system; using the axle torque and speed to approximate damage values for the driveline of the multi-function drive axle system; comparing the approximated values of driveline damage with driveline damage durability targets; identifying if the approximated values of driveline damage exceed the driveline damage durability targets; and limiting the engine torque and/or speed to produce an axle torque and speed corresponding to driveline damage values that do not exceed the driveline damage durability targets.

摘要： A control system for a vehicle having two motors is provided to limit damage on rotary members even if an excessive torque is applied from drive wheels. The control system comprises a first motor, a second motor, and a locking mechanism, and a differential mechanism disposed between the first motor and the drive wheels. The locking mechanism halts one of rotary elements of a differential mechanism when torque of the rotary member is small, and allows the rotary element to rotate when the torque of the rotary member is large. A controller is configured to increase power output of the first motor and decrease power output of the second motor during propulsion on an uneven road surface.

摘要： Methods and systems are disclosed for reducing engine flywheel power reduction of an engine while protecting a drivetrain. The method includes monitoring transmission gear selection; determining reduction in flywheel power to protect the drivetrain; and monitoring engine power consumption by other engine power loads. When other engine power loads consume less power than the reduction in flywheel power to protect the drivetrain, the method includes reducing flywheel power by the power difference. When other engine power loads consume the same or more power than the reduction in flywheel power to protect the drivetrain, the method includes not reducing the flywheel power. Engine power can be consumed by both on-vehicle and off-vehicle power loads. Engine power can be consumed by an electric generator and/or a plurality of inverters, and their power consumption can be monitored. Information and commands can be communicated over a controller area network (CAN) bus.

摘要： In order to reduce drivetrain component wear and tear, a machine monitors for an impending downshift and automatically slows the machine to a speed that keeps engine rpm below a target engine rpm before the downshift is completed. A controller in the machine determines the current speed of the machine and then slows the machine to a new speed associated with the target rpm in the new gear. The controller may simply apply the brakes to slow the machine to the new speed independently of the process of changing gears or may actively delay the gear change until the new speed is achieved.
