A traveling controller for vehicle includes a first computing unit, a traveling control unit, a first calculating unit, a second calculating unit, and a second computing unit. The first calculating unit is configured to calculate estimated positions. The second calculating unit is configured to calculate estimated position reliability on the basis of pieces of positional information, including information on one or more estimated positions. The second computing unit is configured to compute control information on the basis of one or more estimated positions when lane line information is unobtainable. The first calculating unit is configured to calculate one or more estimated positions on the basis of a position on map information of an own vehicle newly calculated on the basis of a planimetric feature acquired as traveling environment information, and the traveling control unit is configured to continue a traveling control until the estimated position reliability becomes equal to or less than a threshold, when the lane line information is unobtainable.

A control device of a vehicle comprises a vehicle control part 61 configured to use a probability distribution of at least one predetermined parameter to calculate an expected value of each of at least one evaluation value and control the vehicle 1 based on the expected value.

A vehicle includes an engine, a continuously variable transmission including an input shaft coupled to the engine, an output shaft, an electric machine, and a gearing arrangement. The electric machine is configured to actuate the gearing arrangement to change a speed ratio between the input and output shafts. A controller is programmed to, responsive to a request to manually shift the transmission to one of a predetermined number of virtual discrete speed ratios and the engine being OFF, command starting of the engine regardless of a driver-demand torque and operate the electric machine to shift the transmission to the one of the speed ratios.

Systems and methods are provided for controlling a transmission. An engine stop-start event may be allowed or denied based on one or more characteristics of the vehicle including the transmission.

An engine start controller for a hybrid vehicle and a method thereof are provided. The engine start controller includes a hybrid starter generator (HSG) that is connected to an engine by a belt, a sensor that is configured to measure an HSG speed, and a processor that applies a starting torque to the HSG. When starting the engine, the processor calculates an HSG speed estimated based on the applied starting torque and calculates an amount of slip of the belt using the HSG speed. In addition, the processor calculates a torque change rate correction value based on the calculated amount of slip, and corrects a rate of change rate in the starting torque based on the torque change rate correction value.

A control system for a hybrid vehicle configured to reduce fuel consumption. A controller is configured to execute a first determination to determine that a required power is less than a reference power, and a second determination to determine that a condition to start an engine is satisfied. If the answers of the first determination and the second determination are YES, a target power of the engine is set to a predetermined power which is greater than the required power, and which can be generated by consuming smaller amount of fuel. Then, the generator is driven by the engine being operated to achieve the predetermined power, and an electric power generated by the generator to be accumulated in a battery is set to a value calculated based on a difference between the target power and the required power.

Non-inverted park lock systems and methods include an engine controller configured to control an engine of a vehicle in communication with a separate transmission controller via a controller area network (CAN), wherein the transmission controller is configured to control a transmission of the vehicle; and a conductor connecting the engine controller to a park lock solenoid disposed in the transmission and configured to move a park pawl to engage/disengage park. The engine controller keeps the park pawl disengaged from park during a power loss malfunction at the transmission controller and the transmission controller keeps the park pawl disengaged from park during a power loss malfunction at the engine controller by maintaining hydraulic pressure in the transmission at a threshold level until park is requested via the shifter.

The powertrain device for a vehicle includes an engine and an automatic transmission, the automatic transmission includes a plurality of friction fastening elements for selectively switching motive power transmitting paths, a predetermined friction fastening element among the plurality of friction fastening elements is a travel-start friction fastening element performing slip control in a travel start, and the powertrain device includes, between the engine and the automatic transmission, a motive power connection-disconnection clutch which is released at least in an engine start and is fastened earlier than the travel-start friction fastening element in a travel start of the vehicle.

A control device for a hybrid vehicle includes a processor being configured to: set a target state of charge of the battery; control the internal combustion engine and rotating electric machine and charging and discharging of the battery to make the hybrid vehicle run, so that a state of charge of the battery becomes the target state of charge; and, in a case where a point inside a restricted region where operation of the internal combustion engine is restricted is set as a destination or a waypoint, set the target state of charge to a lower value when an estimated time of arrival at the destination or the waypoint is a point of time outside a restricted time period when operation of the internal combustion engine is restricted in the restricted region than when the estimated time of arrival is a point of time inside the restricted time period.
