연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

An arrangement and a method are provided for improving performance of a start assist system for an internal combustion engine of a vehicle comprising: a start/stop system, a primary source of electrical energy, a secondary source of electrical energy, an electrical starter motor, an engine control unit, and additional vehicle electrical loads. A start controller is arranged such that the starter motor and engine control unit are operable with power supplied from the primary source of electrical energy at an initial cold starting attempt. If reset of the engine control unit occurs during the first cold starting attempt, the start controller is arranged such that the starter motor is operable with power supplied from the primary source of electrical energy and the engine control unit is operable with power supplied from the secondary source of electrical energy for an additional cold starting attempt.

1. An arrangement for improving the performance of a start assist system for an internal combustion engine of a vehicle, the arrangement comprising: a start/stop system;a primary source of electrical energy;a secondary source of electrical energy;an electrical starter motor;an engine control unit; anda start controller arranged such that the starter motor and engine control unit are operable with power supplied from the primary source of electrical energy at an initial cold starting attempt and such that, if reset of the engine control unit occurs during the initial cold starting attempt, the starter motor is operable with power supplied from the primary source of electrical energy and the engine control unit is operable with power supplied from the secondary source of electrical energy for an additional cold starting attempt. 2. An arrangement according to claim 1 further comprising an additional electrically powered component used in starting the engine, wherein the start controller further is arranged such that the additional electrically powered component, normally operable with power supplied from the primary source of electrical energy, at an initial cold starting attempt, if reset of the engine control unit occurs during the first cold starting attempt, is operable with power supplied from the secondary source of electrical energy for an additional cold starting attempt. 3. An arrangement according to claim 1 wherein the internal combustion engine comprises electrically powered injector valves, and wherein the start controller further is arranged such that the electrically powered injector valves, normally operable with power supplied from the primary source of electrical energy, at an initial cold starting attempt, if reset of the engine control unit occurs during the first cold starting attempt, are operable with power supplied from the secondary source of electrical energy for an additional cold starting attempt. 4. An arrangement according to claim 1 wherein the second source of electrical energy comprises a lithium ion battery. 5. An arrangement according to claim 1 wherein the second source of electrical energy comprises a super capacitor. 6. A vehicle comprising an arrangement according to claim 1. 7. The arrangement according to claim 1 wherein the initial cold starting attempt involves use of a key or a starter button. 8. A method for improving the performance of a start assist system for an internal combustion engine of a vehicle including a start/stop system, a primary source of electrical energy, a secondary source of electrical energy, an electrical starter motor, and an engine control unit, the method comprising: arranging a start controller such that the starter motor and the engine control unit are operable with power supplied from the primary source of electrical energy at an initial cold starting attempt, and such that, if reset of the engine control unit occurs during the initial cold starting attempt, the starter motor is operable with power supplied from the primary source of electrical energy and the engine control unit is operable with power supplied from the secondary source of electrical energy for an additional cold starting attempt. 9. A method according to claim 8 further comprising arranging the start controller such that an additional electrically powered component used in starting the engine, normally operable with power supplied from the primary source of electrical energy, at an initial cold starting attempt, if reset of the engine control unit occurs during the first cold starting attempt, is operable with power supplied from the secondary source of electrical energy for an additional cold starting attempt. 10. A method according to claim 8 further comprising arranging the start controller such that electrically powered injector valves of the internal combustion engine, normally operable with power supplied from the primary source of electrical energy, at an initial cold starting attempt, if reset of the engine control unit occurs during the first cold starting attempt, are operable with power supplied from the secondary source of electrical energy for an additional cold starting attempt. 11. A method according to claim 8 further comprising providing a lithium ion battery as the second source of electrical energy. 12. A method according to claim 8 further comprising providing a super capacitor as the second source of electrical energy. 13. The method according to claim 8 wherein the initial cold starting attempt involves use of a key or a starter button. 14.
