METHOD FOR CONTROLLING SERIES HYBRID VEHICLE, AND SERIES HYBRID VEHICLE
A control method controls a series hybrid vehicle in which a drive motor and an internal combustion engine are supported in a vehicle body via a plurality of mount members in an integrated state. The control method using a controller generates electric power using an electric power generation motor, and drives the electric power generation motor using motive power of the internal combustion engine. The control method drives a drive wheel with the drive motor using the generated electric power, and causes the drive motor to generate regenerative torque during deceleration. In the control method, the regenerative torque is generated by the drive motor such that an upper limit of the regenerative torque is restricted to a magnitude at which an engine rotational speed where resonance occurs on the vehicle body floor.
METHODS AND SYSTEMS FOR OPERATING A VEHICLE SUBJECT TO A TRAVEL RESTRICTION
Systems and methods of operating a vehicle subject to a travel restriction determine when the vehicle is traveling in an unloaded state; determine a speed of the vehicle when the vehicle is traveling in the unloaded state to produce an actual travel empty speed; compare the actual travel empty speed with an historical travel empty speed for the vehicle; and determine that the vehicle operation is subject to the travel restriction when the actual travel empty speed is less than a predetermined percentile of the historical travel empty speed. When the vehicle operation is not subject to the travel restriction, the systems and methods further evaluate vehicle operation based on an established performance parameter for the vehicle under a normal operating condition; and change a vehicle performance parameter during future vehicle operation based on the evaluation.

Real-time performance handling virtual tire sensor
Devices, systems, and methods related to prediction of tire performance using existing CAN data to improve overall vehicle performance. Machine learning tools are applied to CAN data, for example pilot data and/or vehicle dynamics data, to predict tire performance factors for use in a vehicle control system to provide vehicle lateral guidance control.

EHC WARMUP NOTIFICATION
Systems and methods of electrically heating catalyst (EHC) driver notification are provided. With the goal of increasing driver cooperation in reducing emissions, EHC driver notification systems notify the driver when the EHC is in an inefficient operation state. This notification is provided to the driver so that the driver may consciously operate the vehicle in a fashion that reduces emissions while the EHC is in the inefficient operation state. EHC driver notifications systems may also restrict operation of the vehicle when the EHC is in an inefficient operation state. However, for safety reasons, these systems provide the driver a function to bypass the restriction as needed.

Method for determining the drive train sensitivity of a drive train of a motor vehicle
A method for determines the drive train sensitivity of a drive train of a motor vehicle. A vehicle body is placed in longitudinal oscillations in the direction of travel and a parameter for the drive train sensitivity is determined as a function of the determined longitudinal accelerations of the vehicle body and the resultant angular accelerations of a transmission input shaft of a transmission of the motor vehicle.
Vehicle and self-driving control device
A vehicle includes a sensor circuit configured to detect an obstacle in a first region which is located on the predetermined traveling route and in a second region which is adjacent to the first region on the predetermined traveling route, the second region being farther than the first region. The vehicle enters the first region in a case where: there is no obstacle in the first region; and there is no obstacle in the second region, and does not enter the first region and stops before the first region in a case where: there is no obstacle in the first region; and there is an obstacle in the second region.
