A control apparatus for a vehicle that includes: a drive wheel; an engine; a gear-type power transmission device disposed between the engine and the drive wheel; and a rotary electric machine connected to the gear-type power transmission device in a power transmittable manner. The rotary electric machine is configured to apply a pressing torque in order to suppress rattle noise caused by play between gears of the gear-type power transmission device. The control apparatus is configured to detect an engine torque that is a torque of the engine, and to control the pressing torque based on the detected engine torque.

A vehicle includes a battery control module and a controller. The battery control module is configured to issue at regular intervals a message indicative of a state of charge (SOC) of a battery. The controller is configured to, in an absence of receiving the messages at the regular intervals while in a key-on state and a torque demand is present, restrict power flow between the battery and an electric powertrain to a limit that is based on a predicted SOC to provide limited propulsive force.

Inverterless running control is control in which an inverter is set to a gate cut-off state, an engine is driven to mechanically rotate a motor-generator and to generate in the motor-generator, counter-electromotive torque in accordance with a difference between a counter-electromotive voltage of the motor-generator and a system voltage, and a vehicle runs with drive torque applied to an output shaft as reaction force of the counter-electromotive torque. An ECU controls drive torque to produce driving force determined by an accelerator position by raising or lowering the system voltage during inverterless running control.

A series hydraulic hybrid driveline for a vehicle is described. The driveline has a power source, a hydraulic circuit having a first hydraulic displacement unit and a second hydraulic displacement unit, a hydraulic accumulator assembly with high pressure and low pressure hydraulic accumulators, at least one accumulator valve, at least one input device, and a control unit. The first hydraulic displacement unit is drivingly engaged with the power source. The accumulator assembly is selectively fluidly connected to the hydraulic circuit through the accumulator valve.
