Provided are methods for controlling vehicle performance based on data associated with an environmental condition.

A safety system (200) for a vehicle (100) is provided. The safety system (200) may include one or more processors (102). The one or more processors (102) may be configured to control a vehicle (100) to operate in accordance with the predefined stored driving model parameters, to detect vehicle operation data during the operation of the vehicle (100), to determine whether to change predefined driving model parameters based on the detected vehicle operation data and the driving model parameters, to change the driving model parameters to changed driving model parameters, and to control the vehicle (100) to operate in accordance with the changed driving model parameters.

A system, map server and method of navigating a vehicle through an intersection. The map server includes a remote processor and a communication device. The remote processor determines a first road edge for a first road entering an intersection and a second road edge for a second road entering the intersection. The remote processor constructs an intersection edge that connects a first point on the first road edge to a second point on the second road edge. The communication device communicates the intersection edge to the vehicle. A vehicle processor at the vehicle navigates the vehicle through the intersection using the intersection edge.

A notification device includes: a notification-sound output portion provided in a vehicle and configured to output a notification sound toward the outside of the vehicle; a notification display portion provided in the vehicle and configured to output a notification display toward the outside of the vehicle; a notification controlling portion configured to control the notification sound of the notification-sound output portion and the notification display of the notification display portion; and a stop-state determination portion configured to determine whether the vehicle during the automatic driving enters a stop state or not. When the stop-state determination portion determines that the vehicle during the automatic driving enters the stop state, the notification controlling portion outputs a stop-time notification sound as the notification sound by the notification-sound output portion and outputs a stop-time notification display as the notification display by the notification display portion.

Safety apparatus for use in vehicles traveling on roadways. The apparatus including a vehicle with a computer having accelerometers and gyroscopes coupled to provide signals compensating for acceleration, velocity, and centripetal forces produced by movement of the vehicle. A color coded slope map stored in the computer. A simulated color wheel overlying a level bubble matrix within the computer with a fixed orientation relative to the vehicle. The matrix including a simulated bubble floating within the matrix, and the signals applied to the simulated bubble so that the position of the bubble and the color of the bubble is only dependent upon the orientation of the vehicle. The computer comparing or mixing the color of the slope map to the color of the bubble at each location along the slope map and providing a warning when the color of the slope map and the color of the bubble are compliments.

An automotive system providing method for detecting a road in an abnormal state based on a measured value of an acceleration sensor mounted on a vehicle includes an acceleration sensor measuring a value of gravity acceleration acting on a vehicle; a position measuring sensor measuring a position of the vehicle; a memory in which the measured value of the gravity acceleration and the position of the vehicle at a time point at which the gravity acceleration is measured are stored; and a controller electrically connected to the acceleration sensor, the position measuring sensor and the memory and configured for determining a road corresponding to the position where the value of the gravity acceleration is measured as being in an abnormal condition when the controller concludes that a difference value between the value of the gravity acceleration measured during operation of the vehicle and a reference acceleration value added to the value of the gravity acceleration to correct the value of the gravity acceleration as a zero reference point is out of a predetermined threshold range.
