A hybrid vehicle includes an engine (10), a first motor generator (MG1), a second motor generator (MG2), a transmission unit (power transmission unit) (40), a differential unit (50), a clutch (CS) and a mechanical oil pump (501). The hybrid vehicle is able to switch between series-parallel mode in which power of the engine is transmitted via the transmission unit and the differential unit and series mode in which power of the engine is transmitted via the clutch. The differential unit (50) is a planetary gear mechanism including a sun gear (S2) connected to the first motor generator (MG1), a ring gear (R2) connected to the second motor generator (MG2), and a carrier (CA2) connected to a ring gear (R1) that is an output element of the transmission unit (40). The mechanical oil pump (501) is driven by power that is transmitted from the carrier (CA2) of the differential unit.

Described embodiments provide circuits, systems and methods for detecting and communicating fault conditions. In an embodiment, an integrated circuit includes a fault detector to detect a fault condition of the integrated circuit and a controller to generate output data of the integrated circuit. An output generator generates an output signal of the integrated circuit. The output signal is generated at a first set of output levels based upon the output data when the fault detector does not detect the fault condition, and the output signal is generated at a second set of output levels based upon the output data when the fault detector detects the fault condition.

An image of the nearby surroundings of a user's vehicle is displayed, which includes images of the user's vehicle and threshold lines that define a range of distance from the user's vehicle. The image of the nearby surroundings of the user's vehicle is changed in accordance with a positional relationship between another vehicle and the range of distance.

A sliding feedback control system of a vehicle is provided. The system includes: an electric motor; a power battery; a battery manager connected with the power battery, and configured to obtain a maximum charging power of the power battery; and a motor controller connected with the electric motor, and configured to obtain maximum feedback torque values of the motor controller and the electric motor, to convert the maximum charging power of the power battery into a maximum feedback torque value of the power battery, to determine a minimum of the maximum feedback torque values as a first feedback torque value, to obtain a second feedback torque value, and to determine a final feedback torque value of the electric motor as a minimum of the first and second feedback torque values, such that the electric motor controls the vehicle to perform the sliding feedback operation according to the final feedback torque value.

A speed controlling method for a vehicle comprises obtaining a driving speed limit of a road ahead from a navigation system of the vehicle. A current driving speed of the vehicle is detected and if the current driving speed of the vehicle is greater than the limit ahead, a driver of the vehicle is informed that he must slow down in a distance between the vehicle and a speed measuring device located on the road ahead.

A mobile body corrosion measuring apparatus having a corrosion sensor installed in at least one portion of a mobile body, the corrosion sensor measuring a corrosion state at the portion and outputting corrosion data; a vehicle (mobile body) running speed sensor installed in the mobile body, the running speed sensor measuring a running speed of the mobile body and outputting the running speed data; and a data collection unit that acquires the corrosion data from the corrosion sensor and the running speed data from the vehicle speed sensor at the same time and collects the corrosion data and the running speed data with the corrosion data and the running speed data associated with each other. Due to above structure, a corrosion state specific to the mobile body can be accurately measured.
