A control device is configured to perform: performing a first process when an index value indicating a degree of closeness to a risky object which is present in front of a mobile object is less than a first threshold value; performing a second process when the index value is equal to or greater than the first threshold value and less than a second threshold value greater than the first threshold value; and performing a third process and the second process when the index value is equal to or greater than the second threshold value. The third process includes a fourth process of proposing a driving operation for avoiding the risky object to a driver. The fourth process is not performed when the driver has performed an action for reducing or releasing an operation of an operator instructing an accelerating operation for accelerating the mobile object.

An information processing device configured to calculate a feature related to driving of a vehicle includes a first processor configured to receive input information including information on a speed of the vehicle and a second processor configured to calculate the feature by using the input information received during a first period in which predetermined conditions are satisfied. The first period being included in a second period in which the input information is received. The predetermined conditions include a condition that a driving operation is performed before a brief stop of the vehicle.

A method detects a driving state of a vehicle. The vehicle has a drive train with at least one drive and an accelerator pedal. A rest state of the accelerator pedal is determined by evaluating an operating point position of the accelerator pedal by a first accelerator pedal gradient in a first time interval, and checking whether the first accelerator pedal gradient within the first time interval is less than a maximum value.

The vehicle driving force control apparatus executes a mistaken press-down driving force control for setting an upper limit as an initial upper limit for limiting driving force when a mistaken press-down operation of an acceleration pedal is detected. The control apparatus executes a limitation level reduction control when a predetermined vehicle movement is not detected while the mistaken press-down driving force control is executed, and the acceleration pedal is operated. The limitation level reduction control is realized by repeatedly executing a process for limiting the driving force to a first upper limit larger than the initial upper limit for a first period of time and then, limiting the driving force to a second upper limit smaller than the first upper limit for a second period of time. The first upper limit increases as the number of executing the upper limit change process increases.

A propulsion control system provides different levels of jerk as a function of operator inputs and actual measured operational parameters in a machine. The system includes a power source, a continuously variable transmission (CVT) coupled to an output of the power source, a plurality of input/output devices, a plurality of sensors configured to generate signals indicative of operational parameters of the machine, and a controller communicatively coupled with the power source, the CVT, the input/output devices, and the sensors. The controller includes a database stored in a memory with a plurality of jerk values mapped to different operations of the machine selected from at least one of activation of a brake by an operator for an aggressive stop, a directional shift request from an operator to select one of forward, reverse, or neutral, and a set of operating conditions of the machine indicative of a blade load shedding mode. A jerk selection module is programmed to select at least one of a jerk value, an acceleration limit value, and a deceleration limit value based on a current operation of the machine. A speed command generating device is programmed to integrate a selected jerk value twice to generate a desired speed command. A proportional-integral-derivative (PID) control device is configured to continuously calculate a control error between the desired speed command and an actual speed of the machine. An output command control module is configured to output a control command for implementing a change in an output torque to at least one of the power source and the CVT to reduce the control error.

Vehicle acceleration from a learned deceleration area or stop can be learned and/or predicted. While approaching a learned deceleration stop, deceleration data including a current accelerator off speed can be acquired. It can be determined whether there is an acceleration learning record for the learned deceleration stop. Responsive to determining that there is an acceleration learning record for the learned deceleration area, it can be determined whether the current accelerator off speed meets a qualification rule based on one or more prior accelerator off speeds included in the acceleration learning record for the learned deceleration area. Responsive to determining that the current accelerator off speed meets the qualification rule, an acceleration for the vehicle from the learned deceleration area can be predicted. The predicted acceleration can include a cruising speed that is substantially equal to the current accelerator off speed.

Systems and methods for improving operation of a vehicle that includes an engine that may be automatically stopped and started are presented. In one example, vehicle launch control parameters are adjusted responsive to a learned driving style. The approach may provide vehicle launches that are closer to driver expectations than vehicle launches that are based solely on accelerator pedal position.

When an accelerator operating speed is greater than a quick depression threshold value, a start threshold value is set to a value that is smaller than a selection threshold value between a single-drive mode and a double-drive mode in an EV drive mode. Then, when a required torque becomes greater than the start threshold value, an engine is started.

The present disclosure relates to an apparatus (1) for estimation of a vehicle state. The apparatus (1) includes a controller (21) configured to determine a first estimation of the vehicle state in dependence on at least one first vehicle dynamics parameter. A filter coefficient (F.sub.C) is calculated based on a first vehicle operating parameter. An operating frequency of a first signal filter (35) is set in dependence on the determined filter coefficient (F.sub.C) and the first estimation is filtered to generate a first filtered estimation of the vehicle state. The present disclosure also relates to a vehicle; and to a method of estimating a vehicle state.

A fault diagnosis method for a bio-signal sensor for the vehicle includes measuring a first bio-signal through the bio-signal sensor in response to a seating detecting signal, measuring a second bio-signal through the bio-signal sensor in response to input through an on-board interface, and determining whether the bio-signal sensor may have malfunctioned according to whether the second bio-signal includes a signal deviating from a range set in response to the first bio-signal.
