Abstract: A control system for a hybrid vehicle that can prevent an overcharging of a battery even if a wheel speed drops abruptly. The hybrid vehicle comprises: an engine; a generator that is driven by the engine; a drive motor that generate a drive torque; and a battery. The electric power generated by the generator is supplied directly to the battery or the drive motor. A controller is configured to determine whether the drive wheel will be locked, and to reduce the electric power generated by the generator less than an acceptable input power to the battery if the drive wheel is expected to be locked.

Abstract: In a construction in which a turbine and an exhaust gas purification catalyst are arranged close to each other, and in which an exhaust gas sensor is arranged in an exhaust passage between the turbine and the exhaust gas purification catalyst, the exhaust gas sensor is suppressed from getting wet with condensed water. In an exhaust system for an internal combustion engine, an exhaust gas sensor is arranged in a circumferential direction of a specific exhaust passage in a position except a range which is reached by a bypass exhaust gas carried away by a turbine swirling flow.

Abstract: A turbocharger includes a turbine housing and a wastegate. The turbine housing has an accommodation space, is which a turbine wheel is accommodated. The accommodation space is connected to a scroll passage, which draws exhaust gas from the outside of the turbine housing, and a connection passage, which discharges exhaust gas from the accommodation space. The connection passage is connected to a merging passage, which discharges exhaust gas to the outside of the turbine housing. The merging passage is connected to a bypass passage, which bypasses the accommodation space. The central axis of an outlet portion of the connection passage is inclined with respect to the rotation axis of the turbine wheel toward the side on which an outlet portion of the bypass passage is located.

Abstract: In the present invention, a first regeneration process is executed as a process for oxidizing and removing PM accumulated on the particulate filter if a measured value of a differential pressure sensor is not more than a predetermined upper limit value, assuming that the measured value of the differential pressure sensor is a value to be provided in a state in which only PM is accumulated on the particulate filter, when a difference between an estimated PM accumulation amount estimated from an operation history of an internal combustion engine and a PM accumulation amount calculated from the measured value of the differential pressure sensor is not less than a predetermined threshold value, while a second regeneration process is executed without executing the first regeneration process if the measured value is larger than the predetermined upper limit value.

Abstract: An abnormality in an exhaust system component disposed at the downstream side of a particulate filter is determined by using a differential pressure sensor for measuring a differential pressure between a pressure of exhaust gas at the upstream side of the particulate filter and an atmospheric pressure. In an abnormality determination system for an exhaust device according to embodiments of the present invention, a differential pressure at a second flow rate of the exhaust gas different from a first flow rate of the exhaust gas is estimated based on a first actual differential pressure which is a differential pressure measured by the differential pressure sensor and the first flow rate of the exhaust gas which is a flow rate of the exhaust gas at the time when the first actual differential pressure is measured, and when a difference between a second actual differential pressure, which is measured by the differential pressure sensor at the time when the actual flow rate of the exhaust gas is the second flow rate of the exhaust gas, and an estimated differential pressure is equal to or more than a predetermined threshold value, a determination is made that the exhaust system component at the downstream side of the particulate filter is abnormal.
