A braking and driving force control device includes a target braking and driving force calculation unit, and a braking and driving force distribution unit. The braking and driving force distribution unit causes a driving device to generate a target braking and driving force in a case where the target braking and driving force is within the availability, and in a case where the target braking and driving force is less than a lower limit value of the availability, causes the driving device to generate a braking and driving force corresponding to the lower limit value of the availability, performs arithmetic processing of suppressing time variation on the lower limit value of the availability, and causes a braking device to generate a braking force corresponding to a difference between the lower limit value of the availability after the arithmetic processing and the target braking and driving force.

A method for compensating sensor tolerances of accelerometers of a vehicle. The method includes following steps: recording of measurement signals of at least three similarly oriented accelerometers, calculation of an acceleration (a.sub.b,z) at a reference position in the spatial direction, which corresponds to the orientation of the accelerometers, low-pass filtering of the measurement signals, determination of tolerance parameters (c.sub.x, c.sub.y, c.sub.z) of each sensor via an optimization method with the aid of the calculated acceleration (a.sub.b,z) at the reference position, and calculation of the adjusted measurement signals from the recorded measurement signals and the tolerance parameters (c.sub.x, c.sub.y, c.sub.z).

Methods are provided for controlling various systems in a vehicle based on input signals from at least one physical sensor and at least one model of a vehicle or a portion of the vehicle. The controller a rely preferentially on one or the other inputs based on the frequency of a motion of the vehicle and the state of the vehicle or one or mor portions of the vehicle.

This on-vehicle communication apparatus is configured to communicate with another on-vehicle communication apparatus by using one differential signal line, and includes: a high-band communication unit configured to generate a high-band signal including communication information and output the high-band signal to the differential signal line; and a low-band communication unit configured to generate a direct-current signal or a low-band signal and to output the direct-current signal or the low-band signal to the differential signal line.

Disclosed are a vehicle for generating an acceleration profile based on the acceleration cognitive characteristics of the human and a method of controlling the same. The method includes: receiving a manipulation amount of an accelerator pedal and calculating a first torque value, inserting the first torque value to a function that receives force and outputs acceleration feeling, generating a second torque value by inserting an output value of the function into a first filter for stabilizing the output value, generating a target torque value by inputting the second torque value to a second filter for stabilizing the second torque value, and generating a torque command based on the target torque value.

An online method of detecting and compensating for errors in flux estimation in operation of a motor system. The method includes determining a voltage compensation term by comparing an expected voltage and an actual voltage. The method also includes determining a flux compensation term by passing the voltage compensation term through a low-pass filter, and determining a corrected flux component value by comparing the flux compensation term with a flux value obtained from a look-up table, wherein the low-pass filter receives operating parameters based on data regarding an operating environment of the motor system. The method then further determines a corrected torque value based on the corrected flux component value.

Systems and control methods can provide for determining a TrnAin torque request from desired vehicle acceleration in a vehicle that utilizes a WTC architecture to allow for smooth transition between different transmission states, such as torque converter bypass clutch states and shifts between transmission gear ratios. The methods provide consistent and smooth vehicle acceleration profile during transmission state transitions. The methods also provide the ability to track the desired vehicle acceleration consistently from virtual driver demand sources, such as adaptive cruise control, autonomous vehicle, or remote parking, without allocating any additional resource to account for transmission state transitions. The proposed methods are applicable to any TC-based automatic transmission drivetrain, such as conventional powertrain, MHT, P4 HEV, or even BEV powertrains where the motor is located on the impeller side of a torque converter.

Systems and methods for operating a hybrid powertrain that includes an engine and a motor/generator are described. The systems and methods align in time an estimated motor torque and an actual motor torque to provide an estimated driveline torque. The alignment compensates for communications delays between different controllers over a controller area network.

A turning control system of a vehicle includes: a database storing road information; a sensor part to detect a steering angle of a vehicle, a wheel speed of the vehicle, whether the vehicle is accelerated, whether the vehicle is braking, and whether a speed gear of the vehicle is shifted; and a controller that determines whether the vehicle enters a turning section based on one or more pieces of the information detected by the sensor part and the road information stored in the database. In particular, when the vehicle is entering the turning section, the controller sets a target speed of the vehicle and controls a speed of the vehicle to be decelerated to the set target speed.

Provided is a vehicle that can improve vehicle posture control or operation performance during accelerating turn. A vehicle is provided with: a left drive wheel and a right drive wheel connected to a motor; a required drive power amount input device for inputting a required drive power amount; and a required turn amount input device for inputting a required turn amount. The vehicle further includes a turn control device that adjusts a power difference between the left drive wheel and the right drive wheel on the basis of a time derivative value of the required drive power amount in addition to the required turn amount.
